• What is the cause and solution for SAP error message WG081 - Check for double PO not possible. Document &, document category & ?

  The SAP error message:
  WG081 - Check for double PO not possible. Document & , document category &
  
  Meaning / Cause:
  This error occurs during the creation or processing of a Purchase Order (PO) when the system tries to perform a duplicate PO check but cannot complete it. The message indicates that the system attempted to check for a duplicate PO based on certain criteria but failed because the referenced document (with number &) and document category (&) could not be processed or found.
  Common causes include:
  
  The referenced PO document number or document category is missing, incorrect, or inconsistent.
  The system is unable to access or retrieve the referenced PO due to authorization issues or data inconsistencies.
  Custom or standard duplicate check logic is triggered but cannot complete because of missing or invalid data.
  The document category provided is not valid for the duplicate check.
  The PO document is in a status that prevents the duplicate check (e.g., deleted, blocked, or archived).
  
  
  When does it occur?
  
  During PO creation or change (transaction ME21N, ME22N).
  When the system is configured to check for duplicate POs (via configuration or user exit).
  When a user tries to copy or reference an existing PO and the system tries to validate duplicates.
  
  
  Solution / How to fix:
  
  
  Check the PO document number and category:
  
  Verify that the PO number and document category referenced in the error message are correct and exist in the system.
  Use transaction ME23N to display the PO and check its status.
  
  
  
  Check configuration for duplicate PO check:
  
  Duplicate PO check is controlled via user exits or BAdIs (e.g., ME_PROCESS_PO_CUST).
  Review any custom logic that might be causing the check to fail.
  Check if the duplicate check is enabled in your system and if the criteria are correctly set.
  
  
  
  Check authorizations:
  
  Ensure the user has the necessary authorizations to access the PO documents involved in the check.
  
  
  
  Check document status:
  
  Verify that the referenced PO is not deleted, blocked, or archived.
  If the PO is archived, the system might not be able to perform the duplicate check.
  
  
  
  Debug the process:
  
  If you have development support, debug the duplicate check logic to identify why the system cannot perform the check.
  Look into the function modules or methods used for duplicate PO check.
