  Verify Field Existence: Check the target table in the SAP system to confirm whether the field exists. You can do this using transaction codes like SE11 (Data Dictionary) or SE16 (Data Browser).
  Correct Mapping: If the field does not exist, update the mapping configuration in the migration tool to reference the correct field or remove the reference if it is not needed.
  Update Migration Plan: If the table structure has changed, you may need to update your migration plan to align with the current structure of the target table.
  Consult Documentation: Review the documentation for the migration tool you are using to ensure that you are following the correct procedures and that the fields you are trying to use are supported.
