  • What is the cause and solution for SAP error message WTADDI255 - Please enter a reference purchase order number for additionals ?

    SAP Error Message:
    WTADDI255Please 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.

    Solution:

    1. Enter the Reference Purchase Order Number:

      • When posting additional costs, ensure that you provide the correct PO number in the relevant field.
      • This links the additional costs to the correct procurement document and allows proper cost allocation.
    2. Check the Configuration:

      • Verify if the system requires a PO reference for additional costs in your business process.
      • In some cases, configuration settings in Logistics Invoice Verification or Materials Management might enforce this requirement.
    3. Review the Process:

      • If you are posting additional costs without a PO intentionally (e.g., for direct expenses), check if your process allows this or if a workaround is needed.
      • Sometimes, additional costs can be posted without a PO if configured accordingly, but this depends on your system setup.
    4. Consult Documentation or SAP Notes:

      • Check SAP Notes or your internal documentation for any specific instructions related to additional costs and PO references in your SAP environment.
