• What is the cause and solution for SAP error message EDI_SD404 - Raw structure and proxy structure do not match ?

  The SAP error message EDI_SD404, which states "Raw structure and proxy structure do not match," typically occurs in the context of Electronic Data Interchange (EDI) when there is a mismatch between the data structure expected by the SAP system and the data structure being sent or received.
  Cause:
  
  
  Data Structure Mismatch: The raw data structure (the format of the incoming or outgoing EDI message) does not match the expected proxy structure (the internal representation of the data in SAP). This can happen if:
  
  The EDI message format has changed (e.g., due to an update in the EDI standard).
  The mapping between the EDI message and the SAP data structure is incorrect or outdated.
  There are missing or extra fields in the EDI message.
  
  
  
  Configuration Issues: Incorrect configuration in the EDI settings, such as the message type, partner profiles, or mapping settings, can lead to this error.
  
  
  Version Mismatch: If the EDI message is generated by a different version of the software or system that does not align with the expected version in SAP, it can lead to structural mismatches.
  
  
  Solution:
  
  
  Check Mapping: Review the mapping between the EDI message and the SAP structure. Ensure that all required fields are present and correctly mapped. This may involve checking the EDI mapping configuration in transaction codes like WE60 (for documentation) and WE30 (for IDoc types).
  
  
  Update Configuration: If there have been changes to the EDI message format, update the configuration in SAP to reflect these changes. This may involve adjusting the partner profiles (transaction WE20) or the message type settings.
  
  
  Validate EDI Message: Use tools to validate the incoming EDI message against the expected structure. This can help identify any discrepancies in the data format.
  
  
  Check for Updates: Ensure that your SAP system is up to date with the latest patches and updates, as these may include fixes for known issues related to EDI processing.
  
  
  Consult Documentation: Review the SAP documentation for the specific EDI message type you are working with to ensure compliance with the expected structure.
  
  
  Debugging: If the issue persists, consider using debugging tools in SAP to trace the processing of the EDI message and identify where the mismatch occurs.
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as WE02 (to view IDocs), WE19 (to test IDocs), and WE20 (to maintain partner profiles).
  IDoc Types: Understand the IDoc types involved in the EDI process, as they define the structure of the data being exchanged.
  SAP Notes: Check SAP Notes for any known issues or updates related to EDI processing that may address the error you are encountering.
  
  By following these steps, you should be able to identify and resolve the cause of the EDI_SD404 error in your SAP system.
