• What is the cause and solution for SAP error message WG053 - No supply source key for material &, plant & found ?

  Certainly! Here's a detailed explanation for the SAP error message WG053: No supply source key for material &, plant & found:
  
  Error Message
  WG053: No supply source key for material &, plant & found
  
  Cause
  This error occurs when the system cannot find a valid supply source key (also known as a source list entry) for the specified material and plant combination during procurement or MRP (Material Requirements Planning) run.
  
  The supply source key is essential for determining from where the material should be procured or produced.
  It usually refers to a valid source list entry that specifies approved vendors or production sources for the material in the given plant.
  If no source list entry exists or the existing entries are not valid for the current procurement scenario (e.g., validity dates, deletion flag, or source list indicator), the system raises this error.
  
  
  When Does It Occur?
  
  During MRP run when the system tries to plan procurement for a material.
  When creating a purchase requisition or purchase order and the system tries to determine the source of supply.
  When the material master or procurement info records are incomplete or missing.
  If the source list is not maintained or the source list indicator is not set in the material master.
  
  
  Solution
  
  
  Check Source List for the Material and Plant:
  
  Transaction: ME03 (Display Source List)
  Verify if there is a valid source list entry for the material and plant.
  Check validity dates and ensure the entry is not flagged for deletion.
  If no entry exists, create one using ME01 (Create Source List).
  
  
  
  Maintain Source List Indicator in Material Master:
  
  Transaction: MM02 (Change Material Master)
  Go to the Purchasing view.
  Check the field Source List Requirement Indicator (usually field SOBSL).
  If the indicator is set to require a source list, ensure the source list exists.
  If you do not want to enforce source list, you can remove this indicator (not recommended if your company policy requires source lists).
  
  
  
  Check Info Records:
  
  Transaction: ME12 (Change Purchasing Info Record)
  Ensure info records exist for the material and vendor combination.
  Info records can also influence source determination.
  
  
  
  Check if the Material is set for External Procurement:
  
  In the material master (MM02), under the MRP 1 or Purchasing views, check the procurement type.
  If the material is set for in-house production only, no external source list is needed.
  If external procurement is required, source list entries must be maintained.
  
  
  
  Run MRP again after corrections:
  
  Transaction: MD01 or MD02 to run MRP and verify if the error is resolved.
  
  
  
  
  Additional Information
  
  Source List: A source list is a master data object that specifies approved sources of supply (vendors or production plants) for a material in a plant.
  Source List Indicator: This indicator in the material master controls whether the system checks the source list during procurement.
  Procurement Type: Defines whether the material is procured externally or produced in-house.
  Info Records: Contain purchasing data for a material and vendor combination and can influence source determination.
