performance can be Reporting Performance, Load Performance or General Performance.
For improving Report Performance:
-Create Aggregates on Infocubes
-Use OLAP Cache for buffering the query result to reduce burden on database
-Pre-caliculated Web templates helps to distribute workload of running report to off-peak hours and can have report result set ready for very fast access to data.
-Use small amount of result data as starting point of any queries and do the drill down
-Avoid reporting on ODS
-If you use exclusion in reporting (<>), the indices are not used, so avoid using the exclusion but use inclusion.
-Use read mode "read when navigating and expanding the hierarchies"
-Use compression of infocube since the E table is optimized for queries
-Create additional indexes at manage data target - performance tab
-Run DB Statistics often
For improving Load Performance:
-Check the ABAP Coding at transfer and update rules this would make performance slow
-Keep available of more dialog processes available and do load balance to different servers
-Indexes on source tables
-Use fixed lengh files if you load data from a flat files and put the files on the application server
-Prefer to use SAP delivered standard extractors
-Use PSA and Datatarget parallel option in the infopackage load settings
-Start several infopackages parallel with different selection options
-load master data before loading transaction data
For improving General Performance:
-Archieve and delete the old data
-Use line item dimensions for large data
-Use BW statistics cube to monitor the performance
-If you are not going to use ODS for reporting desable the Bex reporting flag
1) Invalid characters while loading: When you are loading data then you may get some special characters like @#$%...e.t.c.then BW will throw an error like Invalid characters then you need to go through this RSKC transaction and enter all the Invalid chars and execute. It will store this data in RSALLOWEDCHAR table. Then reload the data. You won't get any error because now these are eligible chars done by RSKC.
2) IDOC Or TRFC Error: We can see the following error at “Status” Screen:Sending packages from OLTP to BW lead to errorsDiagnosisNo IDocs could be sent to the SAP BW using RFC.System responseThere are IDocs in the source system ALE outbox that did not arrive in the ALE inbox of the SAP BW.Further analysis:Check the TRFC log.You can get to this log using the wizard or the menu path "Environment -> Transact. RFC -> In source system".Removing errors:If the TRFC is incorrect, check whether the source system is completely connected to the SAP BW. Check especially the authorizations of the background user in the source system.Action to be taken:If Source System connection is OK Reload the Data.
3)PROCESSING IS OVERDUE FOR PROCESSED IDOCsDiagnosis IDocs were found in the ALE inbox for Source System that is not updated. Processing is overdue. Error correction: Attempt to process the IDocs manually. You can process the IDocs manually using the Wizard or by selecting the IDocs with incorrect status and processing them manually. Analysis:After looking at all the above error messages we find that the IDocs are found in the ALE inbox for Source System that are not Updated.Action to be taken:We can process the IDocs manually via RSMO -> Header Tab -> Click on Process manually.
4) LOCK NOT SET FOR LOADING MASTER DATA ( TEXT / ATTRIBUE / HIERARCHY )Diagnosis User ALEREMOTE is preventing you from loading texts to characteristic 0COSTCENTER . The lock was set by a master data loading process with therequest number. System response For reasons of consistency, the system cannot allow the update to continue, and it has terminated the process. Procedure Wait until the process that is causing the lock is complete. You can call transaction SM12 to display a list of the locks. If a process terminates, the locks that have been set by this process are reset automatically. Analysis:After looking at all the above error messages we find that the user is “Locked”. Action to be taken:Wait for sometime & try reloading the Master Data manually from Info-package at RSA1.
5) Flat File Loading ErrorDetail Error MessageDiagnosis Data records were marked as incorrect in the PSA. System response The data package was not updated.Procedure Correct the incorrect data records in the data package (for example by manually editing them in PSA maintenance). You can find the error message for each record in the PSA by double-clicking on the record status.Analysis:After looking at all the above error messages we find that the PSA contains incorrect record.Action to be taken:To resolve this issue there are two methods:-i) We can rectify the data at the source system & then load the data.ii) We can correct the incorrect record in the PSA & then upload the data into the data target from here.
6) Object requested is currently locked by user ALEREMOTEDetail Error Message.DiagnosisAn error occurred in BI while processing the data. The error is documented in an error message.Object requested is currently locked by user ALEREMOTEProcedureLook in the lock table to establish which user or transaction is using the requested lock (Tools -> Administration -> Monitor -> Lock entries). Analysis:After looking at all the above error messages we find that the Object is “Locked. This must have happened since there might be some other back ground process runningAction to Be taken : Delete the error request. Wait for some time and Repeat the chain.
Idocs between R3 and BW while extraction:
1)When BW executes an infopackage for data extraction the BW system sends a Request IDoc ( RSRQST ) to the ALE inbox of the source system.Information bundled in Request IDoc (RSRQST) is :
Request Id ( REQUEST )
Request Date ( REQDATE )
Request Time (REQTIME)
Info-source (ISOURCE)
Update mode (UPDMODE )
2)The source system acknowledges the receipt of this IDoc by sending an Info IDoc (RSINFO) back to BW system.The status is 0 if it is ok or 5 for a failure.
3)Once the source system receives the request IDoc successfully, it processes it according to the information in the request. This request starts the extraction process in the source system (typically a batch job with a naming convention that begins with BI_REQ). The request IDoc status now becomes 53 (application document posted). This status means the system cannot process the IDoc further.
4)The source system confirms the start of the extraction job by the source system to BW by sending another info IDoc (RSINFO) with status = 1
5)Transactional Remote Function Calls (tRFCs) extract and transfer the data to BW in data packages. Another info IDoc (RSINFO) with status = 2 sends information to BW about the data package number and number of records transferred
6)At the conclusion of the data extraction process (i.e., when all the data records are extracted and transferred to BW), an info IDoc (RSINFO) with status = 9 is sent to BW, which confirms the extraction process.
When is reconstruction allowed?
1. When a request is deleted in a ODS/Cube, will it be available under reconstruction.
Ans :Yes it will be available under reconstruction tab, only if the processing is through PSA Note: This function is particularly useful if you are loading deltas, that is, data that you cannot request again from the source system
2. Should the request be turned red before it is deleted from the target so as to enable reconstruction
Ans :To enable reconstruction you may not need to make the request red, but to enable repeat of last delta you have to make the request red before you delete it.
3. If the request is deleted with its status green, does the request get deleted from reconstruction tab too
Ans :No, it wont get deleted from reconstruction tab
4. Does the behaviour of reconstruction and deletion differ when the target is differnet. ODS and Cube
Ans :Yes

Error loading master data - Data record 1 ('AB031005823') : Version 'AB031005823' is not valid
ProblemCreated a flat file datasource for uploading master data.Data loaded fine upto PSA.Once the DTP which runs the transformation is scheduled, its ends up in error as below:
SolutionAfter refering to many links on sdn, i found that since the data is from an external file,the data will not be matching the SAP internal format. So it shud be followed that we mark "External" format option in the datasource ( in this case for Material ) and apply the conversion routine MATN1 as shown in the picture below
:Once the above changes are done, the load was successful.Knowledge from SDN forumsConversion takes place when converting the contents of a screen field from display format to SAP-internal format and vice versa and when outputting with the ABAP statement WRITE, depending on the data type of the field.
Check the info:http://help.sap.com/saphelp_nw04/helpdata/en/2b/e9a20d3347b340946c32331c96a64e/content.htmhttp://help.sap.com/saphelp_nw04/helpdata/en/07/6de91f463a9b47b1fedb5be18699e7/content.htmThis fm ( MATN1) will add leading ZEROS to the material number because when u query on MAKT with MATNR as just 123 you wll not be getting any values, so u should use this conversion exit to add leading zeros.’
Function module to make yellow request to RED
Use SE37, to execute the function module RSBM_GUI_CHANGE_USTATE.From the next screen, for I_REQUID enter that request ID and execute.From the next screen, select 'Status Erroneous' radiobutton and continue.This Function Module, change the status of request from Green / Yellow to RED.
What will happend if a request in Green is deleted?
Deleting green request is no harm. if you are loading via psa, you can go to tab 'reconstruction' and select the request and 'insert/reconstruct' to have them back.But,For example you will need to repeat this delta load from the source system. If you delete the green request then you will not get these delta records from the source system.Explanation :when the request is green, the source system gets the message that the data sent was loaded successfully, so the next time the load (delta) is triggered, new records are sent.If for some reason you need to repeat the same delta load from the source, then making the request red sends the message that the load was not successful, so do not discard these delta records.Delta queue in r/3 will keep until the next upload successfully performed in bw. The same records are then extracted into BW in the next requested delta load.
Appearence of Values for charecterstic input help screen
Which settings can I make for the input help and where can I maintain these settings?In general, the following settings are relevant and can be made for the input help for characteristics:Display: Determines the display of the characteristic values with the following options "Key", "Text", "Key and text" and "Text and key".Text type: If there are different text types (short, medium and long text), this determines which text type is to be used to display the text.Attributes: You can determine for the input help which attributes of the characteristic are displayed initially. When you have a large number of attributes for the characteristic, it makes sense to display only a selected number of attributes. You can also determine the display sequence of the attributes.F4 read mode: Determines in which mode the input help obtains its characteristic values. This includes the modes "Values from the master data table (M)", "Values from the InfoProvider (D)" and "Values from the Query Navigation (Q)".
Note that you can set a read mode, on the one hand, for the input help for query execution (for example, in the BEx Analyzer or in the BEX Web) and, on the other hand, for the input help for the query definition (in the BEx Query Designer). You can make these settings in InfoObject maintenance using transaction RSD1 in the context of the characteristic itself, in the InfoProvider-specific characteristic settings using transaction RSDCUBE in the context of the characteristic within an InfoProvider or in the BEx Query Designer in the context of the characteristic within a query. Note that not all the settings can be maintained in all the contexts. The following table shows where certain settings can be made:
Setting RSD1 RSDCUBE BExQueryDesigner
Display X X X
Text type X X X
Attributes X - -
Read mode -
Query execution X X X -
Query definition X - -
Note that the respective input helps in the BEx Web as well as in the BEx Tools enable you to make these settings again after executing the input help.
When do I use the settings from InfoObject maintenance (transaction RSD1) for the characteristic for the input help?
The settings that are made in InfoObject maintenance are active in the context of the characteristic and may be overwritten at higher levels if required. At present, the InfoProvider-specific settings and the BEx Query Designer belong to the higher levels. If the characteristic settings are not explicitly overwritten in the higher levels, the characteristic settings from InfoObject maintenance are active.When do I use the settings from the InfoProvider-specific characteristic settings (transaction RSDCUBE) for the input help?You can make InfoProvider-specific characteristic settings in transaction RSDCUBE -> context menu for a characteristic -> InfoProvider-specific properties.These settings for the characteristic are active in the context of the characteristic within an InfoProvider and may be overwritten in higher levels if required. At present, only the BEx Query Designer belongs to the higher levels. If the characteristic settings are not explicitly overwritten in the higher levels and settings are made in the InfoProvider-specific settings, these are then active. Note that the settings are thus overwritten in InfoObject maintenance.When do I use the settings in the BEx Query Designer for characteristics for the input help?In the BEx Query Designer, you can make the input help-relevant settings when you go to the tab pages "Display" and "Advanced" in the "Properties" area for the characteristic if this is selected.These settings for the characteristic are active in the context of the characteristic within a query and cannot be overwritten in higher levels at present. If the settings are not made explicitly, the settings that are made in the lower levels take effect.
How to supress messages generated by BW Queries
Standard Solution :
You might be aware of a standard solution. In transaction RSRT, select your query and click on the "message" button. Now you can determine which messages for the chosen query are not to be shown to the user in the front-end.
Custom Solution:
Only selected messages can be suppressed using the standard solution. However, there's a clever way you can implement your own solution... and you don't need to modify the system for it!All messages are collected using function RRMS_MESSAGE_HANDLING. So all you have to do is implement an enhancement at the start of this function module. Now it's easy. Code your own logic to check the input parameters like the message class and number and skip the remainder of the processing logic if you don't want this message to show up in the front-end.

How can I display attributes for the characteristic in the input help?
Attributes for the characteristic can be displayed in the respective filter dialogs in the BEx Java Web or in the BEx Tools using the settings dialogs for the characteristic. Refer to the related application documentation for more details.In addition, you can determine the initial visibility and the display sequence of the attributes in InfoObject maintenance on the tab page "Attributes" -> "Detail" -> column "Sequence F4". Attributes marked with "0" are not displayed initially in the input help.
Why do the settings for the input help from the BEx Query Designer and from the InfoProvider-specific characteristic settings not take effect on the variable screen?
On the variable screen, you use input helps for selecting characteristic values for variables that are based on characteristics. Since variables from different queries and from potentially different InfoProviders can be merged on the variable screen, you cannot clearly determine which settings should be used from the different queries or InfoProviders. For this reason, you can use only the settings on the variable screen that were made in InfoObject maintenance.
Why do the read mode settings for the characteristic and the provider-specific read mode settings not take effect during the execution of a query in the BEx Analyzer?
The query read mode settings always take effect in the BEx Analyzer during the execution of a query. If no setting was made in the BEx Query Designer, then default read mode Q (query) is used.
How can I change settings for the input help on the variable screen in the BEx Java Web?
In the BEx Java Web, at present, you can make settings for the input help only using InfoObject maintenance. You can no longer change these settings subsequently on the variable screen.
Selective Deletion in Process Chain
The standard procedure :
Use Program RSDRD_DELETE_FACTS
1. Create a variant which is stored in the table RSDRBATCHPARA for the selection to be deleted from a data target.
2. Execute the generated program.
Observations:
The generated program executes will delete the data from data target based on the given selections. The program also removes the variant created for this selective deletion in the RSDRBATCHPARA table. So this generated program wont delete on the second execution.
If we want to use this program for scheduling in the process chain we can comment the step where the program remove the deletion of the generated variant.
Eg:REPORT ZSEL_DELETE_QM_C10 .

ABAP program to find prev request in cube and delete
There will be cases when we cannot use the SAP built-in settings to delete previous request..The logic to determine previous request may be so customised, a requirement.In such cases you can write a ABAP program which calculates previous request basing our own defined logic.Following are the tables used : RSICCONT ---(list of all requests in any particular cube)RSSELDONE ----- ( has got Reqnumb, source , target , selection infoobject , selections ..etc)Following is one example code. Logic is to select request based on selection conditions used in the infopackage:
TCURF, TCURR and TCURX
TCURF is always used in reference to Exchange rate.( in case of currency translation ).For example, Say we want to convert fig's from FROM curr to TO curr at Daily avg rate (M) and we have an exchange rate as 2,642.34. Factors for this currency combination for M in TCURF are say 100,000:1.Now the effective exchange rate becomes 0.02642.
Question ( taken from sdn ):can't we have an exchange rate of 0.02642 and not at all use the factors from TCURF table?.I suppose we have to still maintain factors as 1:1 in TCURF table if we are using exchange rate as 0.02642. am I right?. But why is this so?. Can't I get rid off TCURF.What is the use of TCURF co-existing with TCURR.Answer :Normally it's used to allow you a greater precision in calaculationsie 0.00011 with no factors gives a different result to0.00111 with factor of 10:1So basing on the above answer, TCURF allows greater precision in calculations.Its factor shud be considered before considering exchange rate
.-------------------------------------------------------------------------------------TCURRTCURR table is generally used while we create currency conversion types.The currency conversion types will refer to the entries in TCURR defined against each currency ( with time reference) and get the exchange rate factor from source currency to target currency.
-------------------------------------------------------------------------------------
TCURXTCURX
table is used to exactly define the correct number of decimal places for any currency. It shows effect in the BEx report output.

How to define F4 Order Help for infoobject for reporting
Open attributes tab of infoobject definition.In that you will observe column for F4 order help against each attribute of that infoobject like below :
This field defines whether and where the attribute should appear in the value help.Valid values:• 00: The attribute does not appear in the value help.•
01: The attribute appears at the first position (to the left) in the value help.•
02: The attribute appears at the second position in the valuehelp.•
03: ......• Altogether, only 40 fields are permitted in the input help. In addition to the attributes, the characteristic itsel, its texts, and the compounded characteristics are also generated in the input help. The total number of these fields cannot exceed 40.
So accordingly , the inofobjects are changed> Suppose if say for infobject 0vendor, if in case 0country ( which is an attribute of 0vendor) is not be shown in the F4 help of 0vendor , then mark 0 against the attribtue 0country in the infoobject definition of 0vendor.
Dimension Size Vs Fact Size
The current size of all dimensions can be monitored in relation to fact table by t-code se38 running report SAP_INFOCUBE_DESIGNS.Also,we can test the infocube design by RSRV tests.It gives out the dimension to fact ratio.
The ratio of a dimension should be less than 10% of the fact table.In the report,Dimension table looks like /BI[C/O]/D[xxx]
Fact table looks like /BI[C/0]/[E/F][xxx]
Use T-CODE LISTSCHEMA to show the different tables associated with a cube.
When a dimension grows very large in relation to the fact table, db optimizer can't choose efficient path to the data because the guideline of each dimension having less than 10 percent of the fact table's records has been violated.
The condition of having large data growth in a dimension is called degenerative dimension.To fix, move the characteristics to different dimensions. But can only be done when no data in the InfoCube.
Note : In case if you have requirement to include item level details in the cube, then may be the Dim to Fact size will obviously be more which you cant help it.But you can make the item charecterstic to be in a line item dimension in that case.Line item dimension is a dimension having only one charecterstic in it.In this case, Since there is only one charecterstic in the dimension, the fact table entry can directly link with the SID of the charecterstic without using any DIMid (Dimid in dimension table usually connects the SID of the charecterstic with the fact) .Since link happens by ignoring dimension table ( not in real sense ) , this will have faster query performance.

1What is tickets? And example?
The typical tickets in a production Support work could be:
1. Loading any of the missing master data attributes/texts.
2. Create ADHOC hierarchies.
3. Validating the data in Cubes/ODS.
4. If any of the loads runs into errors then resolve it.
5. Add/remove fields in any of the master data/ODS/Cube.
6. Data source Enhancement.
7. Create ADHOC reports.
1. Loading any of the missing master data attributes/texts - This would be done by scheduling the info packages for the attributes/texts mentioned by the client.
2. Create ADHOC hierarchies. - Create hierarchies in RSA1 for the info-object.
3. Validating the data in Cubes/ODS. - By using the Validation reports or by comparing BW data with R/3.
4. If any of the loads runs into errors then resolve it. - Analyze the error and take suitable action.
5. Add/remove fields in any of the master data/ODS/Cube. - Depends upon the requirement
6. Data source Enhancement.
7. Create ADHOC reports. - Create some new reports based on the requirement of client.
Tickets are the tracking tool by which the user will track the work which we do. It can be a change requests or data loads or whatever. They will of types critical or moderate. Critical can be (Need to solve in 1 day or half a day) depends on the client. After solving the ticket will be closed by informing the client that the issue is solved. Tickets are raised at the time of support project these may be any issues, problems.....etc. If the support person faces any issues then he will ask/request to operator to raise a ticket. Operator will raise a ticket and assign it to the respective person. Critical means it is most complicated issues ....depends how you measure this...hope it helps. The concept of Ticket varies from contract to contract in between companies. Generally Ticket raised by the client can be considered based on the priority. Like High Priority, Low priority and so on. If a ticket is of high priority it has to be resolved ASAP. If the ticket is of low priority it must be considered only after attending to high priority tickets.
Checklists for a support project of BPS - To start the checklist:
1) Info Cubes / ODS / data targets 2) planning areas 3) planning levels 4) planning packages 5) planning functions 6) planning layouts 7) global planning sequences 8) profiles 9) list of reports 10) process chains 11) enhancements in update routines 12) any ABAP programs to be run and their logic 13) major bps dev issues 14) major bps production support issues and resolution .
2 What are the tools to download tickets from client? Are there any standard tools or it depends upon company or client...?
Yes there are some tools for that. We use Hpopen view. Depends on client what they use. You are right. There are so many tools available and as you said some clients will develop their own tools using JAVA, ASP and other software. Some clients use just Lotus Notes. Generally 'Vantive' is used for tracking user requests and tickets.
It has a vantive ticket ID, field for description of problem, severity for the business, priority for the user, group assigned etc.
Different technical groups will have different group ID's.
User talks to Level 1 helpdesk and they raise ticket.
If they can solve issue for the issue, fine...else helpdesk assigns ticket to the Level 2 technical group.
Ticket status keeps changing from open, working, resolved, on hold, back from hold, closed etc. The way we handle the tickets vary depending on the client. Some companies use SAP CS to handle the tickets; we have been using Vantage to handle the tickets. The ticket is handled with a change request, when you get the ticket you will have the priority level with which it is to be handled. It comes with a ticket id and all. It's totally a client specific tool. The common features here can be - A ticket Id, - Priority, - Consultant ID/Name, - User ID/Name, - Date of Post, - Resolving Time etc.
There ideally is also a knowledge repository to search for a similar problem and solutions given if it had occurred earlier. You can also have training manuals (with screen shots) for simple transactions like viewing a query, saving a workbook etc so that such queried can be addressed by using them.
When the problem is logged on to you as a consultant, you need to analyze the problem, check if you have a similar problem occurred earlier and use ready solutions, find out the exact server on which this has occurred etc.
You have to solve the problem (assuming you will have access to the dev system) and post the solution and ask the user to test after the preliminary testing from your side. Get it transported to production once tested and posts it as closed i.e. the ticket has to be closed.
performance can be Reporting Performance, Load Performance or General Performance.
For improving Report Performance:
-Create Aggregates on Infocubes
-Use OLAP Cache for buffering the query result to reduce burden on database
-Pre-caliculated Web templates helps to distribute workload of running report to off-peak hours and can have report result set ready for very fast access to data.
-Use small amount of result data as starting point of any queries and do the drill down
-Avoid reporting on ODS
-If you use exclusion in reporting (<>), the indices are not used, so avoid using the exclusion but use inclusion.
-Use read mode "read when navigating and expanding the hierarchies"
-Use compression of infocube since the E table is optimized for queries
-Create additional indexes at manage data target - performance tab
-Run DB Statistics often
For improving Load Performance:
-Check the ABAP Coding at transfer and update rules this would make performance slow
-Keep available of more dialog processes available and do load balance to different servers
-Indexes on source tables
-Use fixed lengh files if you load data from a flat files and put the files on the application server
-Prefer to use SAP delivered standard extractors
-Use PSA and Datatarget parallel option in the infopackage load settings
-Start several infopackages parallel with different selection options
-load master data before loading transaction data
For improving General Performance:
-Archieve and delete the old data
-Use line item dimensions for large data
-Use BW statistics cube to monitor the performance
-If you are not going to use ODS for reporting desable the Bex reporting flag
1) Invalid characters while loading: When you are loading data then you may get some special characters like @#$%...e.t.c.then BW will throw an error like Invalid characters then you need to go through this RSKC transaction and enter all the Invalid chars and execute. It will store this data in RSALLOWEDCHAR table. Then reload the data. You won't get any error because now these are eligible chars done by RSKC.
2) IDOC Or TRFC Error: We can see the following error at “Status” Screen:Sending packages from OLTP to BW lead to errorsDiagnosisNo IDocs could be sent to the SAP BW using RFC.System responseThere are IDocs in the source system ALE outbox that did not arrive in the ALE inbox of the SAP BW.Further analysis:Check the TRFC log.You can get to this log using the wizard or the menu path "Environment -> Transact. RFC -> In source system".Removing errors:If the TRFC is incorrect, check whether the source system is completely connected to the SAP BW. Check especially the authorizations of the background user in the source system.Action to be taken:If Source System connection is OK Reload the Data.
3)PROCESSING IS OVERDUE FOR PROCESSED IDOCsDiagnosis IDocs were found in the ALE inbox for Source System that is not updated. Processing is overdue. Error correction: Attempt to process the IDocs manually. You can process the IDocs manually using the Wizard or by selecting the IDocs with incorrect status and processing them manually. Analysis:After looking at all the above error messages we find that the IDocs are found in the ALE inbox for Source System that are not Updated.Action to be taken:We can process the IDocs manually via RSMO -> Header Tab -> Click on Process manually.
4) LOCK NOT SET FOR LOADING MASTER DATA ( TEXT / ATTRIBUE / HIERARCHY )Diagnosis User ALEREMOTE is preventing you from loading texts to characteristic 0COSTCENTER . The lock was set by a master data loading process with therequest number. System response For reasons of consistency, the system cannot allow the update to continue, and it has terminated the process. Procedure Wait until the process that is causing the lock is complete. You can call transaction SM12 to display a list of the locks. If a process terminates, the locks that have been set by this process are reset automatically. Analysis:After looking at all the above error messages we find that the user is “Locked”. Action to be taken:Wait for sometime & try reloading the Master Data manually from Info-package at RSA1.
5) Flat File Loading ErrorDetail Error MessageDiagnosis Data records were marked as incorrect in the PSA. System response The data package was not updated.Procedure Correct the incorrect data records in the data package (for example by manually editing them in PSA maintenance). You can find the error message for each record in the PSA by double-clicking on the record status.Analysis:After looking at all the above error messages we find that the PSA contains incorrect record.Action to be taken:To resolve this issue there are two methods:-i) We can rectify the data at the source system & then load the data.ii) We can correct the incorrect record in the PSA & then upload the data into the data target from here.
6) Object requested is currently locked by user ALEREMOTEDetail Error Message.DiagnosisAn error occurred in BI while processing the data. The error is documented in an error message.Object requested is currently locked by user ALEREMOTEProcedureLook in the lock table to establish which user or transaction is using the requested lock (Tools -> Administration -> Monitor -> Lock entries). Analysis:After looking at all the above error messages we find that the Object is “Locked. This must have happened since there might be some other back ground process runningAction to Be taken : Delete the error request. Wait for some time and Repeat the chain.
Idocs between R3 and BW while extraction:
1)When BW executes an infopackage for data extraction the BW system sends a Request IDoc ( RSRQST ) to the ALE inbox of the source system.Information bundled in Request IDoc (RSRQST) is :
Request Id ( REQUEST )
Request Date ( REQDATE )
Request Time (REQTIME)
Info-source (ISOURCE)
Update mode (UPDMODE )
2)The source system acknowledges the receipt of this IDoc by sending an Info IDoc (RSINFO) back to BW system.The status is 0 if it is ok or 5 for a failure.
3)Once the source system receives the request IDoc successfully, it processes it according to the information in the request. This request starts the extraction process in the source system (typically a batch job with a naming convention that begins with BI_REQ). The request IDoc status now becomes 53 (application document posted). This status means the system cannot process the IDoc further.
4)The source system confirms the start of the extraction job by the source system to BW by sending another info IDoc (RSINFO) with status = 1
5)Transactional Remote Function Calls (tRFCs) extract and transfer the data to BW in data packages. Another info IDoc (RSINFO) with status = 2 sends information to BW about the data package number and number of records transferred
6)At the conclusion of the data extraction process (i.e., when all the data records are extracted and transferred to BW), an info IDoc (RSINFO) with status = 9 is sent to BW, which confirms the extraction process.
When is reconstruction allowed?
1. When a request is deleted in a ODS/Cube, will it be available under reconstruction.
Ans :Yes it will be available under reconstruction tab, only if the processing is through PSA Note: This function is particularly useful if you are loading deltas, that is, data that you cannot request again from the source system
2. Should the request be turned red before it is deleted from the target so as to enable reconstruction
Ans :To enable reconstruction you may not need to make the request red, but to enable repeat of last delta you have to make the request red before you delete it.
3. If the request is deleted with its status green, does the request get deleted from reconstruction tab too
Ans :No, it wont get deleted from reconstruction tab
4. Does the behaviour of reconstruction and deletion differ when the target is differnet. ODS and Cube
Ans :Yes

Error loading master data - Data record 1 ('AB031005823') : Version 'AB031005823' is not valid
ProblemCreated a flat file datasource for uploading master data.Data loaded fine upto PSA.Once the DTP which runs the transformation is scheduled, its ends up in error as below:
SolutionAfter refering to many links on sdn, i found that since the data is from an external file,the data will not be matching the SAP internal format. So it shud be followed that we mark "External" format option in the datasource ( in this case for Material ) and apply the conversion routine MATN1 as shown in the picture below
:Once the above changes are done, the load was successful.Knowledge from SDN forumsConversion takes place when converting the contents of a screen field from display format to SAP-internal format and vice versa and when outputting with the ABAP statement WRITE, depending on the data type of the field.
Check the info:http://help.sap.com/saphelp_nw04/helpdata/en/2b/e9a20d3347b340946c32331c96a64e/content.htmhttp://help.sap.com/saphelp_nw04/helpdata/en/07/6de91f463a9b47b1fedb5be18699e7/content.htmThis fm ( MATN1) will add leading ZEROS to the material number because when u query on MAKT with MATNR as just 123 you wll not be getting any values, so u should use this conversion exit to add leading zeros.’
Function module to make yellow request to RED
Use SE37, to execute the function module RSBM_GUI_CHANGE_USTATE.From the next screen, for I_REQUID enter that request ID and execute.From the next screen, select 'Status Erroneous' radiobutton and continue.This Function Module, change the status of request from Green / Yellow to RED.
What will happend if a request in Green is deleted?
Deleting green request is no harm. if you are loading via psa, you can go to tab 'reconstruction' and select the request and 'insert/reconstruct' to have them back.But,For example you will need to repeat this delta load from the source system. If you delete the green request then you will not get these delta records from the source system.Explanation :when the request is green, the source system gets the message that the data sent was loaded successfully, so the next time the load (delta) is triggered, new records are sent.If for some reason you need to repeat the same delta load from the source, then making the request red sends the message that the load was not successful, so do not discard these delta records.Delta queue in r/3 will keep until the next upload successfully performed in bw. The same records are then extracted into BW in the next requested delta load.
Appearence of Values for charecterstic input help screen
Which settings can I make for the input help and where can I maintain these settings?In general, the following settings are relevant and can be made for the input help for characteristics:Display: Determines the display of the characteristic values with the following options "Key", "Text", "Key and text" and "Text and key".Text type: If there are different text types (short, medium and long text), this determines which text type is to be used to display the text.Attributes: You can determine for the input help which attributes of the characteristic are displayed initially. When you have a large number of attributes for the characteristic, it makes sense to display only a selected number of attributes. You can also determine the display sequence of the attributes.F4 read mode: Determines in which mode the input help obtains its characteristic values. This includes the modes "Values from the master data table (M)", "Values from the InfoProvider (D)" and "Values from the Query Navigation (Q)".
Note that you can set a read mode, on the one hand, for the input help for query execution (for example, in the BEx Analyzer or in the BEX Web) and, on the other hand, for the input help for the query definition (in the BEx Query Designer). You can make these settings in InfoObject maintenance using transaction RSD1 in the context of the characteristic itself, in the InfoProvider-specific characteristic settings using transaction RSDCUBE in the context of the characteristic within an InfoProvider or in the BEx Query Designer in the context of the characteristic within a query. Note that not all the settings can be maintained in all the contexts. The following table shows where certain settings can be made:
Setting RSD1 RSDCUBE BExQueryDesigner
Display X X X
Text type X X X
Attributes X - -
Read mode -
Query execution X X X -
Query definition X - -
Note that the respective input helps in the BEx Web as well as in the BEx Tools enable you to make these settings again after executing the input help.
When do I use the settings from InfoObject maintenance (transaction RSD1) for the characteristic for the input help?
The settings that are made in InfoObject maintenance are active in the context of the characteristic and may be overwritten at higher levels if required. At present, the InfoProvider-specific settings and the BEx Query Designer belong to the higher levels. If the characteristic settings are not explicitly overwritten in the higher levels, the characteristic settings from InfoObject maintenance are active.When do I use the settings from the InfoProvider-specific characteristic settings (transaction RSDCUBE) for the input help?You can make InfoProvider-specific characteristic settings in transaction RSDCUBE -> context menu for a characteristic -> InfoProvider-specific properties.These settings for the characteristic are active in the context of the characteristic within an InfoProvider and may be overwritten in higher levels if required. At present, only the BEx Query Designer belongs to the higher levels. If the characteristic settings are not explicitly overwritten in the higher levels and settings are made in the InfoProvider-specific settings, these are then active. Note that the settings are thus overwritten in InfoObject maintenance.When do I use the settings in the BEx Query Designer for characteristics for the input help?In the BEx Query Designer, you can make the input help-relevant settings when you go to the tab pages "Display" and "Advanced" in the "Properties" area for the characteristic if this is selected.These settings for the characteristic are active in the context of the characteristic within a query and cannot be overwritten in higher levels at present. If the settings are not made explicitly, the settings that are made in the lower levels take effect.
How to supress messages generated by BW Queries
Standard Solution :
You might be aware of a standard solution. In transaction RSRT, select your query and click on the "message" button. Now you can determine which messages for the chosen query are not to be shown to the user in the front-end.
Custom Solution:
Only selected messages can be suppressed using the standard solution. However, there's a clever way you can implement your own solution... and you don't need to modify the system for it!All messages are collected using function RRMS_MESSAGE_HANDLING. So all you have to do is implement an enhancement at the start of this function module. Now it's easy. Code your own logic to check the input parameters like the message class and number and skip the remainder of the processing logic if you don't want this message to show up in the front-end.

How can I display attributes for the characteristic in the input help?
Attributes for the characteristic can be displayed in the respective filter dialogs in the BEx Java Web or in the BEx Tools using the settings dialogs for the characteristic. Refer to the related application documentation for more details.In addition, you can determine the initial visibility and the display sequence of the attributes in InfoObject maintenance on the tab page "Attributes" -> "Detail" -> column "Sequence F4". Attributes marked with "0" are not displayed initially in the input help.
Why do the settings for the input help from the BEx Query Designer and from the InfoProvider-specific characteristic settings not take effect on the variable screen?
On the variable screen, you use input helps for selecting characteristic values for variables that are based on characteristics. Since variables from different queries and from potentially different InfoProviders can be merged on the variable screen, you cannot clearly determine which settings should be used from the different queries or InfoProviders. For this reason, you can use only the settings on the variable screen that were made in InfoObject maintenance.
Why do the read mode settings for the characteristic and the provider-specific read mode settings not take effect during the execution of a query in the BEx Analyzer?
The query read mode settings always take effect in the BEx Analyzer during the execution of a query. If no setting was made in the BEx Query Designer, then default read mode Q (query) is used.
How can I change settings for the input help on the variable screen in the BEx Java Web?
In the BEx Java Web, at present, you can make settings for the input help only using InfoObject maintenance. You can no longer change these settings subsequently on the variable screen.
Selective Deletion in Process Chain
The standard procedure :
Use Program RSDRD_DELETE_FACTS
1. Create a variant which is stored in the table RSDRBATCHPARA for the selection to be deleted from a data target.
2. Execute the generated program.
Observations:
The generated program executes will delete the data from data target based on the given selections. The program also removes the variant created for this selective deletion in the RSDRBATCHPARA table. So this generated program wont delete on the second execution.
If we want to use this program for scheduling in the process chain we can comment the step where the program remove the deletion of the generated variant.
Eg:REPORT ZSEL_DELETE_QM_C10 .

ABAP program to find prev request in cube and delete
There will be cases when we cannot use the SAP built-in settings to delete previous request..The logic to determine previous request may be so customised, a requirement.In such cases you can write a ABAP program which calculates previous request basing our own defined logic.Following are the tables used : RSICCONT ---(list of all requests in any particular cube)RSSELDONE ----- ( has got Reqnumb, source , target , selection infoobject , selections ..etc)Following is one example code. Logic is to select request based on selection conditions used in the infopackage:
TCURF, TCURR and TCURX
TCURF is always used in reference to Exchange rate.( in case of currency translation ).For example, Say we want to convert fig's from FROM curr to TO curr at Daily avg rate (M) and we have an exchange rate as 2,642.34. Factors for this currency combination for M in TCURF are say 100,000:1.Now the effective exchange rate becomes 0.02642.
Question ( taken from sdn ):can't we have an exchange rate of 0.02642 and not at all use the factors from TCURF table?.I suppose we have to still maintain factors as 1:1 in TCURF table if we are using exchange rate as 0.02642. am I right?. But why is this so?. Can't I get rid off TCURF.What is the use of TCURF co-existing with TCURR.Answer :Normally it's used to allow you a greater precision in calaculationsie 0.00011 with no factors gives a different result to0.00111 with factor of 10:1So basing on the above answer, TCURF allows greater precision in calculations.Its factor shud be considered before considering exchange rate
.-------------------------------------------------------------------------------------TCURRTCURR table is generally used while we create currency conversion types.The currency conversion types will refer to the entries in TCURR defined against each currency ( with time reference) and get the exchange rate factor from source currency to target currency.
-------------------------------------------------------------------------------------
TCURXTCURX
table is used to exactly define the correct number of decimal places for any currency. It shows effect in the BEx report output.

How to define F4 Order Help for infoobject for reporting
Open attributes tab of infoobject definition.In that you will observe column for F4 order help against each attribute of that infoobject like below :
This field defines whether and where the attribute should appear in the value help.Valid values:• 00: The attribute does not appear in the value help.•
01: The attribute appears at the first position (to the left) in the value help.•
02: The attribute appears at the second position in the valuehelp.•
03: ......• Altogether, only 40 fields are permitted in the input help. In addition to the attributes, the characteristic itsel, its texts, and the compounded characteristics are also generated in the input help. The total number of these fields cannot exceed 40.
So accordingly , the inofobjects are changed> Suppose if say for infobject 0vendor, if in case 0country ( which is an attribute of 0vendor) is not be shown in the F4 help of 0vendor , then mark 0 against the attribtue 0country in the infoobject definition of 0vendor.
Dimension Size Vs Fact Size
The current size of all dimensions can be monitored in relation to fact table by t-code se38 running report SAP_INFOCUBE_DESIGNS.Also,we can test the infocube design by RSRV tests.It gives out the dimension to fact ratio.
The ratio of a dimension should be less than 10% of the fact table.In the report,Dimension table looks like /BI[C/O]/D[xxx]
Fact table looks like /BI[C/0]/[E/F][xxx]
Use T-CODE LISTSCHEMA to show the different tables associated with a cube.
When a dimension grows very large in relation to the fact table, db optimizer can't choose efficient path to the data because the guideline of each dimension having less than 10 percent of the fact table's records has been violated.
The condition of having large data growth in a dimension is called degenerative dimension.To fix, move the characteristics to different dimensions. But can only be done when no data in the InfoCube.
Note : In case if you have requirement to include item level details in the cube, then may be the Dim to Fact size will obviously be more which you cant help it.But you can make the item charecterstic to be in a line item dimension in that case.Line item dimension is a dimension having only one charecterstic in it.In this case, Since there is only one charecterstic in the dimension, the fact table entry can directly link with the SID of the charecterstic without using any DIMid (Dimid in dimension table usually connects the SID of the charecterstic with the fact) .Since link happens by ignoring dimension table ( not in real sense ) , this will have faster query performance.

1What is tickets? And example?
The typical tickets in a production Support work could be:
1. Loading any of the missing master data attributes/texts.
2. Create ADHOC hierarchies.
3. Validating the data in Cubes/ODS.
4. If any of the loads runs into errors then resolve it.
5. Add/remove fields in any of the master data/ODS/Cube.
6. Data source Enhancement.
7. Create ADHOC reports.
1. Loading any of the missing master data attributes/texts - This would be done by scheduling the info packages for the attributes/texts mentioned by the client.
2. Create ADHOC hierarchies. - Create hierarchies in RSA1 for the info-object.
3. Validating the data in Cubes/ODS. - By using the Validation reports or by comparing BW data with R/3.
4. If any of the loads runs into errors then resolve it. - Analyze the error and take suitable action.
5. Add/remove fields in any of the master data/ODS/Cube. - Depends upon the requirement
6. Data source Enhancement.
7. Create ADHOC reports. - Create some new reports based on the requirement of client.
Tickets are the tracking tool by which the user will track the work which we do. It can be a change requests or data loads or whatever. They will of types critical or moderate. Critical can be (Need to solve in 1 day or half a day) depends on the client. After solving the ticket will be closed by informing the client that the issue is solved. Tickets are raised at the time of support project these may be any issues, problems.....etc. If the support person faces any issues then he will ask/request to operator to raise a ticket. Operator will raise a ticket and assign it to the respective person. Critical means it is most complicated issues ....depends how you measure this...hope it helps. The concept of Ticket varies from contract to contract in between companies. Generally Ticket raised by the client can be considered based on the priority. Like High Priority, Low priority and so on. If a ticket is of high priority it has to be resolved ASAP. If the ticket is of low priority it must be considered only after attending to high priority tickets.
Checklists for a support project of BPS - To start the checklist:
1) Info Cubes / ODS / data targets 2) planning areas 3) planning levels 4) planning packages 5) planning functions 6) planning layouts 7) global planning sequences 8) profiles 9) list of reports 10) process chains 11) enhancements in update routines 12) any ABAP programs to be run and their logic 13) major bps dev issues 14) major bps production support issues and resolution .
2 What are the tools to download tickets from client? Are there any standard tools or it depends upon company or client...?
Yes there are some tools for that. We use Hpopen view. Depends on client what they use. You are right. There are so many tools available and as you said some clients will develop their own tools using JAVA, ASP and other software. Some clients use just Lotus Notes. Generally 'Vantive' is used for tracking user requests and tickets.
It has a vantive ticket ID, field for description of problem, severity for the business, priority for the user, group assigned etc.
Different technical groups will have different group ID's.
User talks to Level 1 helpdesk and they raise ticket.
If they can solve issue for the issue, fine...else helpdesk assigns ticket to the Level 2 technical group.
Ticket status keeps changing from open, working, resolved, on hold, back from hold, closed etc. The way we handle the tickets vary depending on the client. Some companies use SAP CS to handle the tickets; we have been using Vantage to handle the tickets. The ticket is handled with a change request, when you get the ticket you will have the priority level with which it is to be handled. It comes with a ticket id and all. It's totally a client specific tool. The common features here can be - A ticket Id, - Priority, - Consultant ID/Name, - User ID/Name, - Date of Post, - Resolving Time etc.
There ideally is also a knowledge repository to search for a similar problem and solutions given if it had occurred earlier. You can also have training manuals (with screen shots) for simple transactions like viewing a query, saving a workbook etc so that such queried can be addressed by using them.
When the problem is logged on to you as a consultant, you need to analyze the problem, check if you have a similar problem occurred earlier and use ready solutions, find out the exact server on which this has occurred etc.
You have to solve the problem (assuming you will have access to the dev system) and post the solution and ask the user to test after the preliminary testing from your side. Get it transported to production once tested and posts it as closed i.e. the ticket has to be closed.
