  Solution:
  
  Verify MPNs: Check the MPN in the purchasing contract and compare it with the MPN in the source list for the relevant material. Ensure they match.
  Update Source List: If the MPN in the source list is incorrect, update it to reflect the correct MPN that matches the purchasing contract.

  Check Vendor Assignment: Ensure that the vendor associated with the MPN in the source list is the same as the vendor in the purchasing contract.
