  Error Message
  WRF_APC594: Enter a supplier for material &1
  
  Cause
  This error occurs when the system expects a supplier to be specified for a particular material but no supplier has been entered. This typically happens in scenarios involving:
  
  Procurement processes where the material must be linked to a vendor/supplier.
  Material master data or source list maintenance where the supplier information is mandatory.
  Automatic procurement proposals or MRP runs that require a valid supplier for the material.
  Custom validations or user-exits/enhancements that enforce supplier entry for certain materials.
  
  
  When does it occur?
  
  During purchase requisition creation or purchase order creation if the system requires a supplier for the material.
  When running MRP or procurement proposals and the system cannot find a valid supplier for the material.
  While maintaining or validating source lists or info records.
  In custom APC (Advanced Planning and Optimization) scenarios where supplier assignment is mandatory.
  
  
  Solution
  
  
  Enter a valid supplier for the material:
  
  Check the Material Master (transaction MM03) to ensure the material is correctly maintained.
  Maintain the Source List (transaction ME01) for the material with a valid supplier.
  Maintain the Info Record (transaction ME11) for the material and supplier combination.
  Ensure that the supplier is active and valid for the plant and purchasing organization.
  
  
  
  Check Custom Validations or Enhancements:
  
  If this error is triggered by a custom validation or user-exit, review the custom code to understand why the supplier is mandatory.
  Adjust the logic if necessary or ensure the supplier data is maintained accordingly.
  
  
  
  Review Procurement Settings:
  
  Verify the procurement type in the material master (MM02) under the Purchasing view.
  Ensure that the material is set up for external procurement if a supplier is required.
  
  
  
  Run MRP or Procurement Proposals after correction:
  
  After entering the supplier, rerun the MRP or procurement process to confirm the error is resolved.
