  W5071 - No valid sources exist
  
  Cause:
  The warning message W5071 "No valid sources exist" typically occurs during procurement or production processes in SAP when the system cannot find any valid source of supply for a material. This means that, based on the current data and selection criteria, there are no valid purchase info records, source lists, contracts, or planned orders available to fulfill the requirement.
  Common scenarios causing this message include:
  
  No valid source list entries for the material/vendor combination.
  No valid purchase info records for the material/vendor.
  Source list entries or info records exist but are not valid for the required date or plant.
  No valid contracts or scheduling agreements exist.
  The material is not assigned to any source of supply.
  The procurement type or MRP settings do not allow the system to find a source.
  
  
  Solution:
  To resolve the W5071 warning, you should:
  
  
  Check Source List:
  
  Transaction: ME03 (Display Source List)
  Verify if there is a valid source list entry for the material and plant.

  Check Purchase Info Records:
  
  Transaction: ME13 (Display Purchase Info Record)
  Verify if there is a valid purchase info record for the material/vendor combination.

  Check MRP type and source determination settings.
  
  
  
  Check Plant and Vendor Master Data:
