  The SAP error message MDG_GN_RFC004 with the description "No &1 source data - system error" typically indicates that there is an issue with the data retrieval process in the Master Data Governance (MDG) system. This error can occur when the system is unable to find the required source data for a specific operation, which can be due to various reasons.
  Possible Causes:
  
  Missing Data: The source data that the system is trying to access may not exist or may have been deleted.
  Configuration Issues: There may be a misconfiguration in the MDG setup or in the data model that prevents the system from accessing the required data.
  Authorization Issues: The user or the system may not have the necessary authorizations to access the source data.
