  • What is the cause and solution for SAP error message W5126 - This requisition not assigned to a source ?

    Certainly! Here's a detailed explanation for the SAP error message W5126: "This requisition not assigned to a source":


    Error Message

    W5126 - This requisition not assigned to a source


    Cause

    This warning message occurs in SAP Materials Management (MM) when you try to create a Purchase Order (PO) or perform a related procurement activity based on a Purchase Requisition (PR), but the system cannot find a valid source of supply assigned to that requisition.

    In other words, the Purchase Requisition you are trying to process does not have a source of supply (such as a vendor or contract) assigned to it. This can happen because:

    • The Purchase Requisition was created without assigning a source of supply.
    • The source list or outline agreement (contract or scheduling agreement) is not maintained or linked to the requisition.
    • The source assignment was deleted or is invalid.
    • The system is configured to require source assignment for the procurement process you are trying to execute.

    When does it occur?

    • During conversion of a Purchase Requisition to a Purchase Order.
    • When using automatic source determination and no source is found.
    • When the system expects a source assignment but none exists.

    Solution / How to resolve

    1. Assign a Source of Supply to the Purchase Requisition:

      • Go to the Purchase Requisition (ME52N).
      • Check the item details and assign a source of supply manually.
      • You can assign a vendor, contract, or scheduling agreement as the source.
    2. Maintain Source List:

      • Ensure that the source list (transaction ME01) is maintained for the material and plant.
      • The source list should include valid vendors and be valid for the relevant period.
    3. Check Outline Agreements:

      • Verify if there are valid contracts or scheduling agreements (ME31K, ME31L) for the material.
      • Assign these agreements as the source of supply in the PR.
    4. Automatic Source Determination:

      • If you want the system to determine the source automatically, ensure that the source list and outline agreements are properly maintained.
      • Check the configuration for automatic source determination.
    5. Check Configuration Settings:

      • In some cases, the system might be configured to require source assignment.
      • Review the settings in the IMG under Materials Management > Purchasing > Purchase Requisition > Assign Source of Supply.
    6. Recreate or Update the Purchase Requisition:

      • If the PR is old or incomplete, consider recreating or updating it with proper source assignment.

    Additional Information

    • Transaction Codes:

      • ME52N: Change Purchase Requisition
      • ME53N: Display Purchase Requisition
      • ME21N: Create Purchase Order
      • ME01: Maintain Source List
      • ME31K: Create Contract
      • ME31L: Create Scheduling Agreement
    • Related Notes:

      • SAP Notes related to source assignment issues can provide further guidance.
      • Check for any custom validations or user exits that might enforce source assignment.
    • Best Practice:

      • Always maintain source lists and outline agreements before creating purchase requisitions.
      • Use automatic source determination to reduce manual errors.

    If you provide more context (e.g., transaction used, process step), I can help tailor the solution further.
