  The SAP error message FMUP126 indicates that there is an issue with the return value from a Business Add-In (BAdI) implementation, specifically the BAdI FMRI->FMRI_BADI_12. This BAdI is typically related to the Funds Management (FM) module in SAP.
  Cause:
  The error occurs when the return value from the BAdI implementation does not match the expected values. The allowed return values are:
  
  ' ' (blank)

  Test the Changes:
  
  After making the necessary changes, test the BAdI implementation to ensure that it now returns a valid value and that the error no longer occurs.
  
  
  
  Check for Other Implementations:
