• What is the cause and solution for SAP error message /LSIERP/TQ135 - Payment lot &1 is being processed by user &2 ?

  The SAP error message /LSIERP/TQ135 Payment lot &1 is being processed by user &2 indicates that a specific payment lot (identified by &1) is currently being processed by another user (identified by &2). This typically occurs in scenarios where multiple users are trying to access or process the same payment lot simultaneously, leading to a lock situation.
  Cause:
  
  Concurrent Access: Another user is currently processing the payment lot, which prevents other users from accessing it until the first user completes their task.
  Session Lock: The payment lot may be locked due to a previous session that did not close properly or is still active.
  Long-running Transactions: If the transaction is taking longer than expected, it may lead to this error if another user tries to access the same lot.
  
  Solution:
  
  Wait and Retry: The simplest solution is to wait for the other user to finish processing the payment lot and then try again.
  Identify the User: If you have the necessary permissions, you can check which user is currently processing the payment lot. This can be done using transaction codes like SM12 (to view locks) or SM66 (to view active processes).
  Contact the User: If possible, communicate with the user who is processing the payment lot to understand when they expect to finish.
  Check for Stuck Sessions: If you suspect that a session is stuck, you can check for any long-running transactions and terminate them if necessary (with caution).
  System Administrator: If the issue persists, it may be necessary to involve a system administrator to investigate further, especially if there are issues with session management or locks that are not being released.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks), SM21 (to check system logs), and SM66 (to monitor active processes).
  User Communication: Establish a protocol for users to communicate when they are processing payment lots to avoid conflicts.
  Documentation: Ensure that there is proper documentation and training for users on how to handle payment lots to minimize the chances of concurrent processing issues.
  
  By following these steps, you should be able to resolve the error and prevent it from occurring in the future.
