  The SAP error message MDG_MDF127, which states "Definition of role &1 has changed," typically occurs in the context of SAP Master Data Governance (MDG) when there are changes made to the role definition that affect the current configuration or usage of that role.
  Cause:
  
  Role Definition Changes: The error is triggered when the role definition (e.g., authorizations, permissions, or attributes) has been modified after it was initially assigned to a user or a process. This could happen due to updates in the system, changes in business processes, or adjustments made by administrators.
