What is APO/Live cache ?

Home

Advanced Planner and Optimizer (APO) is a set of software application

According to SAP literature, Advanced Planner and Optimizer are designed to help a company improve production planning, pricing, scheduling, and product shipping. APO works by getting real-time updates from SAP R/3 system about customer demand. The updates are used to create APO "demand triggers" that take into account many complex variables, such as the delivery schedule of raw materials and productions cycles, to forecast the right amount of product mix the company will need to meet future customer demands. APO can be integrated with the SAP R/3 and legacy enterprise resource planning (ERP) systems.

APO consists of eight below application levels:

1.      Network design,

2.      Demand planning,

3.      Supply network planning,

4.      Production planning and detailed scheduling,

5.      Global availability,

6.      Transportation planning

7.      Vehicle scheduling,

8.     Supply chain collaboration. 

live cache:

As APO system requires large amount of data to be available all the time and APO also requires this large data to be made available permanently and changeable. 

To fulfill this requirement of APO, SAP has done some changes in their OLTP data structure and added one more database component as LIVE CACHE.

Live cache made SAP DB OLTP relational database system to enable actual data structures and data flows (such as networks and relationships) to be mapped more easily and effectively.

 Live Cache is object-oriented and, unlike SAP DB OLTP, operates with its data only in the main memory of the database system, if configured optimally
