Answer 1

SAP Note says 968812
There are various reasons for verified differences:
1. You made direct FI postings to material balance sheet accounts.
2. In MM account determination, balance sheet accounts are used for operations other than 'BSX'.
3. Material documents exist that have no FI follow-on document, even though they should.
4. There are FI documents or other accounting documents but the source document in materials management is missing.
Solution
(Point 1)
The amounts from these postings do not have any equivalent in the material valuation and therefore cause the MM/FI differences. You must cancel the corresponding postings in FI. You must then set the 'Post automatically only' indicator (XINTB) in the account master record (fs00).
(Point 2)
In MM account determination, material stock accounts can only be assigned during operation 'BSX' because only these postings update the material valuation. Postings from other operations, such as price difference (PRD) or revaluations (UMB), lead to MM/FI differences. The balances resulting from this must be transferred to other accounts in FI.
(Point 3)
Your system contains active customer enhancements (user exits, customer exits, BAdIs) that cause an additional 'COMMIT WORK' statement to be processed. This is not allowed and results in inconsistencies. The incorrect documents can be corrected by SAP Remote Consulting (SAP employees should refer to internal Note 941721).
(Point 4)
This case is identical with case 3. However, usually it is not a 'COMMIT WORK' statement that is responsible but a 'ROLLBACK WORK' statement in the customer source code. In particular, method MB_DOCUMENT_BEFORE_UPDATE in BAdI MB_DOCUMENT_BADI creates a ROLLBACK without program termination and an incomplete document because the documents in accounting are created after the BADI. Therefore, a ROLLBACK must always be accompanied by a program termination.
The MM document cannot be regenerated. The accounting documents must be deleted. This can be initiated by a message (which may be subject to charges) on component FO-GL-GL-X. See also Note 636442.
(General)
If the cause of the problem is unclear, SAP support can run an analysis. In this case, first implement the additional reports from Note 32236 in your production system.
