  The SAP error message USMD1A012 indicates that there is an issue with the configuration of the data model in the SAP Master Data Governance (MDG) application.

  Validate Data Model:
  
  After making changes, validate the data model to ensure that all relationships are correctly configured.
  Use the MDG tools to check for any inconsistencies or errors in the data model.
