  Use Correct BAPI: Verify that you are using the correct BAPI for the reversal operation. Consult the SAP documentation or your technical team to ensure that the BAPI is appropriate for the task.

  Consult SAP Notes: Check for any relevant SAP Notes that may address this specific error message. SAP frequently updates its knowledge base with solutions to common issues.
