• What is the cause and solution for SAP error message 881151 - Declaration already in process by &1 ?

  The SAP error message 881151, "Declaration already in process by &1," typically occurs in the context of tax declarations or similar processes where a declaration is being handled in the system. This error indicates that a declaration is already being processed by another user or session, which prevents the current user from initiating the same process.
  Cause:
  
  Concurrent Processing: The most common cause of this error is that another user or session is already processing the same declaration. SAP does not allow multiple users to process the same declaration simultaneously to maintain data integrity.
  Session Lock: Sometimes, a session may not have been properly closed, leaving a lock on the declaration.
  Long-running Processes: If a previous process is taking longer than expected, it may still be holding the lock on the declaration.
  
  Solution:
  
  Wait and Retry: If another user is processing the declaration, you may need to wait until they complete their task. You can check with your colleagues to see if they are working on the same declaration.
  Check for Active Sessions: Use transaction codes like SM12 (to check for locks) or SM21 (to check system logs) to identify if there are any active sessions or locks on the declaration.
  Terminate Long-running Processes: If you identify a session that is stuck or taking too long, you may need to terminate it. This should be done with caution and typically requires appropriate authorizations.
  Contact SAP Support: If the issue persists and you cannot identify the cause, it may be necessary to contact SAP support for further assistance.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and delete locks), SM21 (to view system logs), and SM37 (to monitor background jobs).
  User Communication: Ensure that users are aware of the processes they are working on to avoid overlapping efforts.
  System Configuration: Review system settings related to locking mechanisms and concurrent processing to ensure they align with your organization's needs.
  
  By following these steps, you should be able to resolve the error and continue with your declaration process.
