  The SAP error message MDG_MSG_HANDLING001 typically indicates an issue with the message handling in the Master Data Governance (MDG) module. The specific error message suggests that there is an incorrect use of the message handler, which may be due to the message ID (MSGID), message type (MSGTY), or message number (MSGNO) being initialized or not properly defined.
  Cause:
  
  Incorrect Message Configuration: The message handler may not be configured correctly, leading to the system not being able to find the appropriate message.

  Custom Code Issues: If there are custom enhancements or modifications in the MDG process, they might be causing the message handling to fail.
