MDG_MDF404 - Details

• The SAP error message MDG_MDF404 indicates that a specific object (such as a master data record) is already locked by another user. This typically occurs in the context of SAP Master Data Governance (MDG) when multiple users attempt to edit the same record simultaneously.
  
  Cause:
  The error message is triggered when:
  
  A user is currently editing a master data record, and another user tries to access or modify the same record.
  The system uses a locking mechanism to prevent data inconsistencies that could arise from concurrent modifications.
  
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Wait for Release: If the record is locked by another user, the simplest solution is to wait until that user has finished editing and released the lock.
  
  
  Identify the Lock: You can identify which user has locked the record by using transaction code SM12 (Lock Entries). Here, you can see the list of locks and the users who hold them.
