  • What is the cause and solution for SAP error message WG309 - PO created for supplier/plant &1 &2, simulation cannot be deleted ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WG309 - PO created for supplier/plant &1 &2, simulation cannot be deleted


    Meaning / Cause:

    This error occurs when you try to delete a purchase requisition (PR) simulation or a purchase requisition item that has already been converted into a purchase order (PO) for the specified supplier (&1) and plant (&2).

    In SAP MM, once a purchase requisition has been converted into a purchase order, the system prevents deletion of the original simulation or requisition item to maintain data consistency and avoid inconsistencies in procurement documents.


    Cause Details:

    • The purchase requisition simulation or item is linked to an existing purchase order.
    • The system enforces integrity by not allowing deletion of requisition data that has already been used to create a PO.
    • This is a standard SAP control to prevent orphaned or inconsistent procurement data.

    Solution / How to Resolve:

    1. Check if PO exists:

      • Verify if a purchase order has been created for the supplier and plant mentioned in the error.
      • Use transaction ME23N (Display Purchase Order) or ME22N (Change Purchase Order) to check the PO.
    2. Do not delete the simulation:

      • Since the PO exists, you cannot delete the simulation or requisition item.
      • Instead, if changes are needed, modify the PO directly or create a new requisition.
    3. If deletion is necessary:

      • You must first delete or cancel the purchase order that was created from the requisition simulation.
      • After the PO is deleted or canceled, you can delete the simulation or requisition item.
      • Note: Deleting a PO requires appropriate authorization and business approval.
    4. Alternative approach:

      • If the PO is still valid, consider creating a new requisition or modifying the existing PO rather than deleting the simulation.

    Additional Information:

    • This message is part of SAP's standard checks in the Materials Management (MM) module.
    • The message helps maintain procurement document integrity.
    • The message text can be found in message class WG.
    • The placeholders &1 and &2 represent the supplier and plant respectively.

    Summary:
