  The SAP error message:
  WP504 EDI: IDOC no. & is invalid
  
  Cause:
  This error occurs when an IDoc number referenced in the EDI processing is not valid or does not exist in the system. The IDoc number might be incorrect, missing, or the IDoc might have been deleted or not yet created. It can also happen if the IDoc number format is wrong or if the IDoc is not properly registered in the database.
  Common scenarios causing this error:
  
  The IDoc number passed to the function/module is incorrect or empty.
  The IDoc has been archived or deleted.
  The IDoc number format does not conform to expected standards.
  The IDoc is not yet created or committed in the database.
  A program or user is trying to process an IDoc that does not exist.
  
  
  Solution:
  
  
  Verify the IDoc number:
  
  Check the IDoc number being used in the process.
  Ensure it exists in the system by using transaction WE02 or WE05 to display the IDoc.
  
  
  
  Check IDoc status:
  
  Confirm the IDoc is not deleted or archived.
  If archived, retrieve it or use the archive information system.
  
  
  
  Correct the IDoc number format:
  
  Ensure the IDoc number is passed correctly without extra spaces or invalid characters.
  
  
  
  Check the program or process:
  
  If a custom program or user exit is involved, debug to verify the IDoc number is correctly fetched and passed.
  Ensure the IDoc is created before processing.
  
  
  
  Reprocess or recreate the IDoc:
  
  If the IDoc is missing, recreate or reprocess the IDoc generation step.
  
  
  
  Check authorization:
  
  Sometimes, lack of authorization to view or process the IDoc can cause this error.
