  The enqueue error ENQUEUE_E_TMC4 indicates that the system failed to obtain a lock on a particular SAP object or table record.
  This can happen due to:
  
  The lock object is already locked by another user or process.
  A deadlock situation or lock wait timeout.
  Inconsistent or stale lock entries in the enqueue table.
  Issues with the enqueue server or enqueue work process.
  Custom code or enhancements that incorrectly handle locks.
  
  
  
  
  2. Explanation of the Error Components
  
  VO715: This is the message number related to the lock operation failure.
