    SAP Error Message:

    W5124 Field & could not be changed in PO item & &


    Meaning / Cause:

    This warning message occurs when you try to change a field in a Purchase Order (PO) item that is not allowed to be changed due to system or business logic restrictions.

    Common causes include:

    • The PO item is already processed or partially processed (e.g., goods receipt or invoice receipt posted).
    • The field is controlled by the system and locked after certain processing steps.
    • The field is dependent on other data that restricts changes.
    • The PO is in a status that does not allow changes to that particular field.
    • The field is part of a reference document or contract where changes are restricted.

    Typical Fields That Cannot Be Changed:

    • Material Number
    • Plant
    • Account Assignment Category
    • Purchasing Group (in some cases)
    • Delivery Date (if goods receipt already posted)
    • Price (if invoice receipt already posted)

    Solution / How to Resolve:

    1. Check PO Status:

      • Verify if the PO or PO item has already been partially or fully processed (e.g., goods receipt or invoice receipt posted).
      • Use transaction ME23N to display the PO and check the item history tab.
    2. Check Document Flow:

      • If the PO is referenced by other documents (e.g., contracts, scheduling agreements), some fields may be locked.
      • Review related documents and their statuses.
    3. Use Change Restrictions:

      • Understand that some fields are intentionally locked to maintain data consistency.
      • If a change is necessary, consider canceling or reversing related documents (e.g., cancel goods receipt or invoice receipt) before making changes.
    4. Create a New PO or PO Item:

      • If changes are not possible, create a new PO or new PO item with the correct data.
    5. Consult Customizing or Development:

      • Sometimes, user exits or BAdIs enforce additional restrictions.
      • Check with your SAP MM consultant or developer if custom logic is preventing changes.
    6. Check Authorization:

      • Ensure you have the necessary authorization to change the PO fields.

    • Message Class: ME (Purchasing)
