WTADDI255 - Details

• SAP Error Message:
  WTADDI255 – Please enter a reference purchase order number for additionals
  
  
  Cause:
  This error occurs in SAP Warehouse Management (WM) or Inventory Management (IM) when you are trying to post additional costs (such as freight, insurance, or other additional expenses) to a goods receipt or invoice receipt without specifying a reference purchase order (PO) number. The system requires a reference PO to correctly assign these additional costs to the relevant procurement document.
  In other words, when entering additional costs related to a goods receipt or invoice, SAP expects you to link these costs to a specific PO. If this reference is missing, the system throws the WTADDI255 error.
  
  When does it typically occur?
  
  During the posting of additional costs in transaction codes related to invoice verification or goods receipt.
  When using the Additional Costs functionality in Logistics Invoice Verification (LIV).
  When entering additional costs manually or via automatic processes without a PO reference.
