  • What is the cause and solution for SAP error message WG030 - No supply source can be found for external req. no. &, material no. & ?

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


    SAP Error Message:

    WG030 No supply source can be found for external req. no. &, material no. &


    Meaning / Cause:

    This error occurs during the processing of an external procurement requisition (purchase requisition or dependent requirement) when the system cannot find any valid supply source (such as a source list entry, outline agreement, or info record) for the specified material.

    In other words, SAP is trying to determine from where the material should be procured externally, but no suitable source of supply is maintained or valid for the material in question.

    Common causes include:

    • No source list maintained for the material and plant combination.
    • Source list exists but is not valid for the date of the requisition.
    • No valid outline agreement (contract or scheduling agreement) exists for the material.
    • Info records missing or not valid for the vendor/material/plant.
    • The material master is not flagged for external procurement or relevant procurement type is missing.
    • The plant or purchasing organization data is incomplete or incorrect.

    When does it occur?

    • During purchase requisition creation or conversion to purchase order.
    • During MRP run when the system tries to determine procurement proposals.
    • When creating dependent requirements or planned orders that require external procurement.
    • When the system tries to find a source of supply for subcontracting or external procurement.

    Solution / How to fix:

    1. Check Source List:

      • Transaction: ME01 (Create Source List), ME03 (Display Source List)
      • Verify if a source list entry exists for the material and plant.
      • Ensure the source list entry is valid for the date of the requisition.
      • If missing, create a source list entry with the appropriate vendor and validity dates.
    2. Check Outline Agreements:

      • Transaction: ME33K (Display Contract), ME33L (Display Scheduling Agreement)
      • Verify if there is a valid outline agreement for the material and vendor.
      • If missing, create or maintain the contract or scheduling agreement.
    3. Check Info Records:

      • Transaction: ME13 (Display Purchasing Info Record)
      • Verify if info records exist and are valid for the vendor/material/plant.
      • Maintain or update info records if necessary.
    4. Material Master Data:

      • Transaction: MM02 (Change Material Master)
      • Check the Purchasing view of the material.
      • Ensure the procurement type is set to external procurement (e.g., 'F' for external procurement).
      • Check if the plant data is maintained correctly.
    5. Check Plant and Purchasing Organization Data:

      • Ensure the plant is assigned to the correct purchasing organization.
      • Verify that the purchasing organization is responsible for the plant.
    6. Check MRP Settings:

      • Ensure that the MRP type and procurement type are consistent.
      • If the material is planned for external procurement, the system must find a source.
    7. Check Vendor Master Data:

      • Ensure the vendor is valid and not blocked.
      • Vendor must be assigned to the purchasing organization.

    Additional Notes:

    • If the system is configured to require source list entries (via the plant parameters or purchasing settings), absence of a source list will cause this error.
    • Sometimes, the error can be bypassed by changing the procurement type to internal if appropriate.
    • If subcontracting is involved, ensure the BOM and subcontracting info records are maintained.
    • Use transaction ME5A to display purchase requisitions and check the source of supply status.

    Summary:
