  Solution:
  
  Check EDI Message Structure: Review the EDI message being sent to ensure that the header and item type codes are correctly defined and match the expected values in SAP.
  Verify Configuration: Check the configuration settings in SAP for EDI processing. Ensure that the header and item type codes are correctly mapped and that the system is set up to handle the specific types of documents being processed.

  Consult Documentation: Refer to SAP documentation or EDI guidelines for the specific types of documents you are processing to ensure compliance with the expected formats and codes.
  Testing: After making changes, conduct tests with sample EDI messages to ensure that the issue is resolved and that the system processes the messages correctly.
