• What is the cause and solution for SAP error message PSSC_BUFFER214 - Enqueue: Object &1 &2 &3 already in use by &4 ?

  The SAP error message PSSC_BUFFER214 indicates that an enqueue object is already in use by another process. This typically occurs when multiple processes attempt to access the same resource simultaneously, leading to a conflict. The message format is as follows:
  Enqueue: Object &1 &2 &3 already in use by &4
  Where:
  
  &1, &2, &3 represent the object type and key.
  &4 indicates the user or process that currently holds the lock.
  
  Cause
  The error can be caused by several factors:
  
  Concurrent Access: Multiple users or processes are trying to access or modify the same object at the same time.
  Long-running Transactions: A transaction that takes a long time to complete may hold a lock on an object longer than expected.
  Deadlocks: Situations where two or more processes are waiting for each other to release locks can also lead to this error.
  Improper Lock Management: If the application logic does not properly manage locks, it can lead to contention.
  
  Solution
  To resolve the PSSC_BUFFER214 error, consider the following steps:
  
  
  Identify the Lock Holder: Use transaction code SM12 to check which user or process is holding the lock. You can filter by the object type and key to find the specific lock.
  
  
  Wait and Retry: If the lock is held by a legitimate process, you may need to wait for that process to complete before retrying your action.
  
  
  Terminate the Lock: If the lock is held by a process that is no longer active or is stuck, you may need to delete the lock entry in SM12. Be cautious with this approach, as it can lead to data inconsistency if the process is still running.
  
  
  Review Application Logic: If this error occurs frequently, review the application logic to ensure that locks are being managed properly. Ensure that locks are released as soon as they are no longer needed.
  
  
  Optimize Long-running Transactions: If certain transactions are taking too long, consider optimizing them to reduce the time locks are held.
  
  
  Check for Deadlocks: Monitor for deadlocks using transaction SM21 (System Log) or ST22 (Dump Analysis) to identify and resolve any deadlock situations.
