  1. Cause
  
  The error WG413 typically occurs during the creation or processing of a Purchase Order (PO) in SAP.
  The message indicates that two accounting documents (FI documents) were generated for a single PO, which is unexpected and considered an error.

  Problems in the document splitting or posting logic in Financial Accounting.
  In some cases, it can be caused by a system bug or inconsistency in the document flow.

  The placeholder &1 in the message will show the FM name causing the issue.
  Analyze the FM to understand why two documents are generated.
  
  
  
  Review Custom Code / Enhancements:
  
  Check for any user exits, BADIs, or enhancements related to PO creation or release that might cause double posting.
  Debug the process to see if the FM is called twice or if the posting logic is executed twice.
  
  
  
  Check Document Flow and Posting Logic:
  
  Verify if the PO is linked to multiple accounting documents.
  Check if document splitting or parallel accounting is causing multiple documents.
