• What is the cause and solution for SAP error message PQ045 - The key was already changed in another session ?

  The SAP error message PQ045, which states "The key was already changed in another session," typically occurs in the context of working with master data or transactional data in SAP, particularly when multiple users or sessions are trying to modify the same data simultaneously. This can lead to conflicts, as SAP locks the data to prevent inconsistencies.
  
  Cause:
  
  Concurrent Access: The most common cause of this error is that another user or session has already changed the key or data you are trying to modify. SAP uses locks to ensure data integrity, and if one session has locked the data, another session will not be able to make changes until the lock is released.
  Session Timeout: If a session is left open for too long without activity, it may time out, and any changes made in that session may not be recognized by other sessions.
  Data Consistency: The system is designed to maintain data
