What to check
A commit failure may follow a validation or database error earlier in the operation. Custom transaction-notification logic is one area to inspect, but the headline message does not prove it is responsible. Preserve the first failure and confirm the outcome before retrying.
Troubleshooting steps
- Capture the full SAP and database messages, transaction timing, and whether the intended document was actually created.
- Have the responsible developer review recent validation changes and reproduce the smallest failing operation in a test company.
- Correct the identified issue using supported development procedures and test both accepted and rejected business cases.
Confirm the result
Verify that the successful case posts once and that legitimate validation still blocks invalid data. Do not disable transaction validation globally to make a single operation succeed.
