• What is the cause and solution for SAP error message ET021 - User & already working on & of & ?

  The SAP error message ET021 typically indicates that a user is already working on a particular object or transaction, which prevents another user from accessing it simultaneously. This is a common issue in SAP systems where multiple users may attempt to access the same data or transaction at the same time.
  
  Cause:
  
  Locking Mechanism: SAP uses a locking mechanism to prevent data inconsistencies. When a user opens a transaction or object, it is locked for editing by other users until the first user completes their task or explicitly releases the lock.
  Long-running Transactions: If a user has a transaction open for an extended period, it can lead to this error for others trying to access the same transaction.
  Session Management: Sometimes, a user may have multiple sessions open, and one of them is already working on the object in question.
  
  
  Solution:
  
  Wait and Retry: If the user can wait, they should try to access the transaction
