  The SAP error message USMD1064 indicates that there is a missing "qualifying" relationship for a specific entity type in the data model you are working with in SAP Master Data Governance (MDG). This error typically arises when the system expects a relationship to be defined that qualifies how entities are related to one another, but it has not been set up correctly.

  Ensure that the relationship is marked as "qualifying" if required by the data model.
  
  
  
  Validate the Data Model:
  
  After defining the relationship, validate the data model to ensure that there are no other issues.
  Use the MDG tools to check for consistency and correctness in the data model.
  
  
  
  Test the Changes:
