  The SAP error message WRF_WSUBST028 indicates that there is no valid supply source for a specific material in a designated receiving plant. This error typically arises in the context of materials management and supply chain processes, particularly when trying to create or process a purchase order, stock transfer, or similar transaction.
  Causes:
  
  
  Missing Source of Supply: The material may not have a valid source of supply defined in the system for the specified receiving plant. This could be due to missing vendor information or a lack of purchasing info records.
  
  
  Incorrect Plant or Material Configuration: The material may not be set up correctly for the receiving plant, or the plant may not be assigned to the material in the material master data.
  
  
  Inactive or Blocked Vendors: The vendor associated with the material may be inactive or blocked, preventing the system from recognizing it as a valid supply source.
  
  
  Invalid or Missing Purchase Info Records: There may be no purchase info records for the material and vendor combination, or the existing records may not be valid for the specified plant.
  
  
  Material Status: The material may have a status that prevents it from being procured or supplied.
