  Review Mapping Configuration: Ensure that the mapping configuration for the vendor numbers is set up correctly. This includes checking transformation rules and ensuring that all necessary fields are included.
  Check Dependencies: Investigate any dependencies related to the vendor numbers. Ensure that all related records are accounted for and that there are no references to the old vendor numbers that could cause conflicts.
  Consult SAP Documentation: Refer to SAP's official documentation or notes related to the specific migration tool you are using. There may be specific guidelines or patches available for your version of SAP.
