3781808 - Unable to Reverse Account Maintenance Document Due to Error FCO_AVC_PS002 in SAP S/4HANA Cloud Public Edition

Unable to reverse the Account Maintenance document due to error FCO_AVC_PS002: "The budget tolerance limit of 100.00% for WBS element  has been reached."

SAP S/4HANA Cloud Public Edition

1. Reverse the FI document with document type KP (Account Maintenance).
2. Open the Display/Cancel Account Maintenance Document app.
3. Select the corresponding Account Maintenance document.
4. Choose Cancel/Reverse.
5. Execute the reversal.

The budget tolerance limit of 100.00% for the WBS element has been reached, causing the system to block the reversal.

The original Account Maintenance document has already consumed the budget. However, in SAP's Availability Control (AVC), each posting is validated on its own before it is saved, and the budget check does not net a reversal against the original document. 

During the reversal attempt:
- The reversal creates a new FI document that would release budget once posted.
- Before that document is saved, AVC runs a pre-check to verify sufficient budget exists.
- At the time of the check, the system will check the available budget on the WBS element.
- Because the available budget is not sufficient, the system raises error FCO_AVC_PS002 and blocks the posting.

To prevent this issue, the Account Maintenance document should be reversed the Account Maintenance document first via the Display/Cancel Account Maintenance Document Fiori app, which should trigger the corresponding FI reversal as part of the same process. And it should increase the budget for the affected WBS element above 100% to allow the reversal to proceed successfully.
