• What is the cause and solution for SAP error message WRMA_FI201 - An IDoc can only have one header segment ?

  The SAP error message:
  WRMA_FI201: An IDoc can only have one header segment
  
  Cause:
  This error occurs during IDoc processing when the system detects that an IDoc contains more than one header segment of the same type. According to the IDoc structure rules, each IDoc must have exactly one header segment (e.g., E1EDK01 for ORDERS, E1EDK02 for delivery, etc.). If multiple header segments are present, the system cannot process the IDoc correctly, leading to this error.
  Common causes include:
  
  Incorrect IDoc generation logic in the sending system or middleware.
  Custom enhancements or user exits incorrectly adding multiple header segments.
  Data mapping or interface errors causing duplication of header segments.
  Corrupted or manually edited IDoc data.
  
  
  Solution:
  To resolve this error, you need to ensure that the IDoc contains only one header segment.
  Steps to troubleshoot and fix:
  
  
  Check the IDoc structure:
  
  Use transaction WE02 or WE05 to display the IDoc.
  Verify the segments under the IDoc header.
  Confirm that only one header segment (e.g., E1EDK01) exists.
  
  
  
  Identify the source of multiple header segments:
  
  If the IDoc is generated by a custom program or middleware, review the logic that creates the IDoc segments.
  Check any user exits, BADIs, or enhancements that might add segments.
  Review the mapping or interface configuration to ensure it does not duplicate header segments.
  
  
  
  Correct the IDoc generation logic:
  
  Modify the program or mapping to add only one header segment.
  Remove or prevent duplicate header segments from being created.
  
  
  
  Reprocess or regenerate the IDoc:
  
  After correction, regenerate the IDoc and test.
  If the IDoc is inbound, request the sender to resend the corrected IDoc.
  
  
  
  Additional checks:
  
  If the IDoc was manually edited, avoid manual changes to the header segment.
  Check for any SAP Notes related to your specific IDoc type or scenario.

  Summary:
  WRMA_FI201 indicates that the IDoc contains more than one header segment, which is not allowed. The solution is to ensure only one header segment exists by correcting the IDoc generation or mapping logic and then reprocessing the IDoc.
