• What is the cause and solution for SAP error message MDC_HDB_MTC064 - Match configuration &1 is currently locked by user &2 ?

  The SAP error message MDC_HDB_MTC064 indicates that a match configuration (in the context of SAP HANA) is currently locked by another user. This typically occurs when one user is making changes to a match configuration, and another user attempts to access or modify the same configuration simultaneously.
  Cause:
  
  Concurrent Access: The primary cause of this error is that the match configuration is being edited or accessed by another user, which locks the configuration to prevent conflicting changes.
  Long-Running Transactions: If a user has a long-running transaction that has not been committed or rolled back, it can keep the configuration locked.
  Session Issues: Sometimes, a session may not release the lock properly due to network issues or application errors.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish their work and then try again. You can check with your team to see if someone is currently working on the match configuration.
  Identify the Locking User: If you have the necessary permissions, you can identify the user who is holding the lock. This can often be done through transaction codes or system views that show active sessions and locks.
  Release the Lock: If you have administrative privileges, you may be able to forcibly release the lock. However, this should be done with caution, as it may lead to data inconsistency or loss of unsaved changes.
  Check for Long-Running Transactions: If a transaction is taking too long, you may need to investigate and resolve any issues causing the delay.
  Contact Support: If the issue persists and you cannot identify the cause, consider reaching out to your SAP support team for assistance.
