• What is the cause and solution for SAP error message WG013 - Trigger update not successful for external req. number & ?

  SAP Error Message:
  
  WG013 - Trigger update not successful for external req. number &
  
  Cause:
  This error occurs in SAP Workflow (often in the context of Purchase Requisitions or other external documents) when the system tries to trigger a workflow update for an external document number (e.g., a Purchase Requisition number), but the update fails. The failure can be due to several reasons such as:
  
  The workflow container or event is not properly configured or missing.
  The external document number referenced does not exist or is incorrect.
  The workflow triggering mechanism (e.g., event linkage) is not properly set up.
  Authorization issues preventing the update.
  Inconsistent or incomplete data in the document or related tables.
  The workflow runtime environment is not active or has errors.
  
  
  Solution:
  To resolve the WG013 error, follow these steps:
  
  
  Check the External Document Number:
  
  Verify that the external requisition number (e.g., Purchase Requisition number) exists and is valid.
  Check if the document is in a status that allows workflow triggering.
  
  
  
  Verify Workflow Configuration:
  
  Ensure that the workflow is correctly linked to the event that triggers it.
  Use transaction SWETYPV to check event linkage for the object type (e.g., BUS2012 for Purchase Requisition).
  Confirm that the event triggering the workflow is active and correctly configured.
  
  
  
  Check Workflow Container and Binding:
  
  Use transaction SWDD to inspect the workflow definition.
  Verify that the workflow container has the correct attributes and that the external document number is properly passed and bound.
  
  
  
  Check Workflow Logs:
  
  Use transaction SWI1 or SWI2_FREQ to check workflow logs for errors or warnings related to the triggering.
  Look for any runtime errors or missing data.
  
  
  
  Authorization Check:
  
  Ensure the user triggering the workflow has the necessary authorizations.
  Check for authorization errors in the workflow logs or system logs.
  
  
  
  Check for System or Transport Issues:
  
  Sometimes, missing transports or incomplete system updates can cause workflow inconsistencies.
  Verify that all relevant workflow objects and event linkages are transported correctly.
  
  
  
  Re-trigger the Workflow:
  
  If the initial trigger failed, try to manually trigger the workflow again using transaction SWUE or program RSWFTRIG.
  
  
  
  Check for SAP Notes:
  
  Search SAP Support Portal for notes related to WG013 for your SAP version.
  Apply any relevant patches or corrections.
