  Check Dependencies: Identify the dependent records that are affected by the assignment change. You may need to adjust or remove these dependencies before making the assignment change.
  Use Transaction Codes: Utilize transaction codes like MDG_MAT for material master data or BP for business partner data to analyze and manage the records involved.
  Consult Documentation: Refer to SAP documentation or notes related to the specific version of MDG you are using. There may be specific guidelines or patches available that address this issue.
