• What is the cause and solution for SAP error message 9P453 - & batch input session already created ?

  The SAP error message 9P453 typically indicates that a batch input session has already been created for the transaction you are trying to execute. This can occur when multiple attempts are made to create a batch input session for the same transaction without processing or deleting the previous session.
  Cause:
  
  Existing Batch Input Session: The most common cause is that a batch input session for the same transaction is already in the system and has not been processed or deleted.
  Concurrent Execution: If multiple users or processes are trying to create a batch input session for the same transaction simultaneously, it can lead to this error.
  Session Locking: The session may be locked due to a previous execution that is still in progress or has not been properly closed.
  
  Solution:
  
  
  Check Existing Sessions:
  
  Go to transaction SM35 (Batch Input Monitoring) to check for existing batch input sessions.
  Look for sessions related to the transaction you are trying to execute. If you find one, you can either process it or delete it if it is no longer needed.
  
  
  
  Process the Session:
  
  If the existing session is valid and needs to be processed, you can execute it from the SM35 transaction.
  
  
  
  Delete the Session:
  
  If the existing session is not needed, you can delete it from the SM35 transaction. Select the session and choose the delete option.
  
  
  
  Avoid Concurrent Execution:
  
  Ensure that the same transaction is not being executed by multiple users or processes at the same time to prevent this error from occurring.
  
  
  
  Check for Locks:
  
  If you suspect that a session is locked, you can check for locks using transaction SM12. If you find any locks related to the batch input session, you may need to release them.
  
  
  
  Related Information:
  
  Batch Input Sessions: These are used in SAP to process large volumes of data by simulating user input. They are created when you use transaction codes like SHDB (Batch Input Recorder) or when executing batch input programs.
  Transaction Codes:
  
  SM35: Batch Input Monitoring
  SHDB: Batch Input Recorder
  SM12: Display and Delete Locks
  
  
  Error Handling: Always ensure to handle errors gracefully in your batch input programs to avoid leaving sessions in an inconsistent state.
  
  By following these steps, you should be able to resolve the error message 9P453 and manage your batch input sessions effectively.
