USMD1A219 - Details

• The SAP error message USMD1A219 indicates that a user has attempted to select a key that has already been selected by another user or process in the context of the SAP Master Data Governance (MDG) application. This typically occurs when multiple users are trying to work on the same data object simultaneously, leading to a conflict.
  
  Cause:
  
  Concurrent Access: The primary cause of this error is that the key (e.g., a business partner, material, or customer) is already being processed or edited by another user.
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When one user selects a key for editing, it locks that key for other users until the first user completes their action.
  Session Timeout: If a user has an open session that has timed out, the lock may not be released properly, causing this error for other users.
  
  
  Solution:
  
  Check for Active Sessions: Verify if another user is currently editing
