• What is the cause and solution for SAP error message RSENQ224 - Cannot remove lock ?

  The SAP error message RSENQ224 "Cannot remove lock" typically occurs when there is an issue with the lock entries in the SAP system. This error is related to the enqueue mechanism, which is responsible for managing locks on objects in the SAP environment to ensure data consistency and integrity.
  Causes:
  
  Active Sessions: The lock cannot be removed because there are still active sessions or processes that are holding the lock.
  Database Issues: There may be issues with the database that prevent the lock from being released.
  System Errors: A system error or inconsistency in the enqueue table can lead to this issue.
  User Authorization: The user attempting to remove the lock may not have the necessary authorizations to do so.
  Long-Running Transactions: If a transaction is taking too long to complete, it may hold onto locks longer than expected.
  
  Solutions:
