WG000 - Details

• The SAP error message:
  WG000 Client missing in header record, external requirement number &
  typically occurs in the context of SAP Warehouse Management (WM) or Logistics Execution (LE) processes, especially when dealing with transfer orders, deliveries, or external requirement documents.
  
  Cause
  
  The error indicates that the client information (SAP system client number) is missing in the header record of an external requirement document.
  The external requirement number (e.g., delivery number, transfer order number) is passed to a function/module or interface, but the system cannot find or identify the client in the header data.
  This usually happens when:
  Data is being transferred between systems or modules without the client field being properly populated.
  Custom programs or interfaces (IDocs, BAPIs, user exits) do not set the client field in the header structure.
  The external requirement document is incomplete or corrupted.
  There is a mismatch or missing configuration in the integration between SAP modules (e.g., SD to WM).
  
  
  
  
  Solution
