Symptom
Error message FF785 "Correct the tax reporting date" happens when posting or reversing supplier invoice in app "Create Supplier Invoice", "Create Supplier Invoice - Advanced (MIRO)" or "Cancel Supplier Invoice Document (MR8M)".
Environment
SAP S/4HANA Cloud
Cause
In standard system when posting or reversing supplier invoice, system checks if the tax reporting date is before the posting date and before the invoice date. If it is, it will raise an error message FF785 "Correct the tax reporting date", which cannot be avoided.
Resolution
There are two options to avoid this error:
1) Please adjust the tax reporting date or posting date so that the tax reporting date is not before both the posting date and invoice date.
2) It is not possible to change the tax reporting date when reversing invoice. Please consider following options:
- Post a credit memo instead of reversing supplier invoice. It is allowed to change tax reporting date when creating credit memo.
- Check KBA 2825513 - "Cloud BAdI for Tax Reporting Date Derivation in Reversals" and use the BADI to enable this posting.
