• What is the cause and solution for SAP error message WG001 - Order type missing in header record, external requirement number & ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WG001 - Order type missing in header record, external requirement number &
  
  Cause:
  This error occurs when the system expects an order type in the header record of a goods movement or production order, but it is missing or not maintained. The external requirement number (displayed as "&" in the message) refers to the specific document or transaction where this issue was detected.
  In SAP, the order type is a key field that defines the characteristics and processing rules of an order (e.g., production order, maintenance order). If this is missing in the header, the system cannot process the order correctly.
  
  When does this happen?
  
  During goods receipt or goods issue postings related to production or maintenance orders.
  When interfacing with external systems or uploading data where the order type is not provided.
  When creating or processing orders where mandatory fields are not filled.
  During batch input or data migration if the order type field is omitted.
  
  
  Solution:
  
  
  Check the Order Header Data:
  
  Go to the order in question (e.g., production order, maintenance order).
  Verify that the order type is maintained in the header.
  Transaction codes like CO02 (Change Production Order) or IW32 (Change Maintenance Order) can be used.
  
  
  
  Maintain the Order Type:
  
  If missing, enter the correct order type.
  The order type should be consistent with the business process and configured in the system.
  
  
  
  Check the External Requirement Number:
  
  Identify the external requirement number mentioned in the error.
  Trace back to the document or interface sending this data.
  Ensure that the order type is correctly passed or mapped.
  
  
  
  Review Customizing:
  
  Check the configuration for order types in SPRO under:
  
  Production Orders: Production -> Shop Floor Control -> Order -> Order Types
  Maintenance Orders: Plant Maintenance -> Maintenance and Service Processing -> Maintenance and Service Orders -> Functions and Settings for Order Types
  
  
  Ensure that the order type is properly defined and active.
  
  
  
  Data Upload / Interface Fix:
  
  If the error occurs during data upload or interface processing, correct the source data to include the order type.
  Validate the mapping in IDocs, BAPIs, or other integration tools.
  
  
  
  Consult SAP Notes:
  
  Sometimes, specific SAP Notes address this error in certain contexts.
