  Meaning / Cause:
  This error occurs when you try to assign or use a supplier (&1) as a source of supply for an additional item or component (&2), but the system does not recognize this supplier as valid for that particular item.
  In other words, the supplier you are trying to add or assign is not maintained or allowed as a source of supply for the specified material or component in the system.
  
  Common Causes:
  
  
  Supplier not maintained in source list:
  
  The supplier is not listed in the source list for the material/component.
  
  
  Supplier not maintained in info record:
  
  The purchasing info record for the material and supplier combination does not exist or is incomplete.
  
  
  Material master data issues:
  
  The material or component does not have the supplier assigned as a valid source.
  
  
  Incorrect configuration or master data:
  
  The system configuration or master data setup does not allow the supplier to be used for the additional item.
  
  
  
  How to Solve / Resolution:
  
  
  Check Source List:  
  
  Go to transaction ME01 (Maintain Source List) or ME03 (Display Source List).  
  Verify if the supplier (&1) is maintained as a valid source for the material/component (&2).  
  If not, add the supplier to the source list for the material.
  
  
  
  Check Purchasing Info Record:  
  
  Use transaction ME11 (Create Purchasing Info Record) or ME12 (Change Purchasing Info Record).  
  Ensure that the info record exists for the supplier and material combination.  
  If missing, create or update the info record.
  
  
  
  Check Material Master Data:  
  
  Verify the material master (MM02) to ensure the material is correctly maintained and that the procurement type and source list indicator are set properly.
  
  
  
  Check Additional Item Configuration:  
  
  If this is related to a BOM or variant configuration, ensure that the additional item/component is correctly linked and that the supplier is valid for it.
  
  
  
  Check Vendor Master Data:  
  
  Ensure the vendor master data is active and valid for purchasing.
  
  
  
  Consult with Purchasing Team:  
  
  Sometimes, business rules restrict certain suppliers for specific materials. Confirm with purchasing or master data team if the supplier should be allowed.
