• What is the cause and solution for SAP error message FK045 - Transaction is currently locked by another user ?

  The SAP error message FK045, which states "Transaction is currently locked by another user," typically occurs when a user attempts to access a transaction or data that is currently being processed or edited by another user. This locking mechanism is a part of SAP's concurrency control to ensure data integrity and prevent conflicts.
  Causes:
  
  Concurrent Access: Another user is currently processing the same transaction or data.
  Session Timeout: A previous session may not have been properly closed, leaving a lock on the transaction.
  Long-running Transactions: A transaction that takes a long time to complete can hold locks for an extended period.
  System Errors: Occasionally, system errors or crashes can leave locks in place.
  
  Solutions:
  
  Wait and Retry: If the lock is temporary, waiting for the other user to complete their transaction may resolve the issue.
  Identify the Lock: Use transaction codes like SM12 (Display and Delete Locks) to identify which user or session is holding the lock. You
