Summary :
This SAP Note addresses errors when accessing planned orders in parallel transactions, particularly during backflush operations in Transaction MF70. Errors such as RM738 and discrepancies in open planned order quantities arise due to a lack of updates to PLAF despite updates to backflush tables (BLPK and BLPR) and material postings occurring simultaneously. The note specifies that these issues occur under the separate backflush setting (aggregate collective backflush), possibly compounded by planning transactions or unrelated updates. The solution involves setting exclusive locks on PLAF during backflush updates and using SET UPDATE TASK LOCAL to serialize updates correctly, thus mitigating such inconsistencies.
