• What is the cause and solution for SAP error message WG012 - Order header update not successful for external req. no. & ?

  SAP Error Message:
  
  WG012 - Order header update not successful for external req. no. &
  
  Cause:
  This error typically occurs during the creation or update of a production order or process order when the system tries to update the order header with an external requisition number (external requirement number), but the update fails. The external requisition number is often linked to a demand source such as a sales order, planned order, or production order from an external system or module.
  Common causes include:
  
  Lock conflicts: The order header record is locked by another user or process, preventing the update.
  Authorization issues: The user or background job does not have sufficient authorization to update the order header.
  Data inconsistencies: The external requisition number or related data is invalid or inconsistent.
  Custom enhancements or user exits: Custom code in user exits or BAdIs that handle order updates may cause the update to fail.
  Database or system errors: Underlying database issues or system errors during the update process.
  
  
  Solution:
  To resolve the WG012 error, consider the following steps:
  
  
  Check for Locks:
  
  Use transaction SM12 to check if the order header or related tables are locked.
  If locks exist, determine if they are stale and can be released.
  
  
  
  Verify Authorizations:
  
  Ensure the user or background job has the necessary authorizations to update production/process orders.
  Check roles and profiles assigned to the user.
  
  
  
  Validate External Requisition Number:
  
  Confirm that the external requisition number being passed is correct and exists in the system.
  Check if the external requisition number is already assigned to another order, causing conflicts.
  
  
  
  Review Custom Code:
  
  If there are user exits, BADIs, or enhancements related to order creation or update (e.g., COHV_UPDATE, WORKORDER_UPDATE), debug or review them for errors.
  Temporarily disable custom code to see if the error persists.
  
  
  
  Check System Logs and Dumps:
  
  Use SM21 (system log) and ST22 (short dumps) to find related error messages or dumps that provide more details.
  
  
  
  Recreate or Update the Order:
  
  Try to manually update the order header or recreate the order to see if the problem is reproducible.
  If the order is corrupted, consider deleting and recreating it if business processes allow.
