• What is the cause and solution for SAP error message /EACC/DMEXTR001 - DataSource &1 is currently locked by user &2 ?

  The SAP error message /EACC/DMEXTR001 DataSource &1 is currently locked by user &2 indicates that a specific DataSource (identified by &1) is currently locked by another user (identified by &2). This typically occurs in the context of data extraction processes, where multiple users or processes may attempt to access or modify the same DataSource simultaneously.
  Cause:
  
  Concurrent Access: Another user or process is currently using the DataSource, which prevents your session from accessing it.
  Long-running Processes: A data extraction or transformation process may be taking longer than expected, causing the lock to persist.
  Unfinished Transactions: If a previous transaction was not completed properly, it may leave the DataSource in a locked state.
  
  Solution:
  
  Wait and Retry: If the lock is temporary, waiting for a few moments and then retrying the operation may resolve the issue.
  Identify the Locking User: Use transaction SM12 to check for locks. You can search for the user (&2) to see what locks they have and if they can be released.
  Contact the Locking User: If possible, communicate with the user who has locked the DataSource to understand if they can release it or if they are done with their operation.
  Release Locks: If you have the necessary authorizations, you can manually release the lock using transaction SM12. Be cautious with this approach, as it may disrupt the other user's work.
  Check for Long-running Jobs: Use transaction SM37 to check for any long-running jobs that might be holding the lock. If you find any, you may need to wait for them to complete or discuss with the responsible team.
  System Monitoring: Implement monitoring to track DataSource usage and avoid future locking issues.
