Runtime "ASSERTION_FAILED" Error when opening RSA1/RSPC

Due to an infinite loop a TIME_OUT dump in CL_RSAWBN_TREE_VIEW or in CL_RSAWBN_TREE_MODEL_FOLDER in method ADD_T_TREE is triggered
Runtime Error ASSERTION_FAILED in ABAP Program CL_RSAWBN_TREE_VIEW is generated
Implement Notes 1585456 and 1618577 and call the transaction again.

Only if point 1 does not help

Remove the entries from table RSCOMPTLOGOT where
APPLNM = 'HYBR' or
APPLNM = 'NODESNOTCONNECTED'

Test again RSA1 or RSPC, if dump persists delete the contents of table RSCOMPTLOGO
Another option is to transport object RSDC with key RSPC from dev/test to move the tree structure into the system.

Obs.: The entries from tables RSCOMPTLOGO/RSCOMPTLOGOT are representing the folder structure of process chains (RSA1/RSPC).  This has no functional influence and the chains, loads etc will still work properly.

If this linked list becomes inconsistent, the only solution is to drop the content of the mentioned tables.

After the entries are deleted, the next call of RSPC will rebuild the list. As the hierarchy structure itself is lost, the newly created folder list will be a flat structure. To return to the desired hierarchical structure, the folders are to be manually positioned to the desired place.
