• What is the cause and solution for SAP error message LF193 - User &1 already logged on to client &2 ?

  The SAP error message LF193 indicates that a user is already logged on to a specific client in the SAP system. This can happen for various reasons, such as a user attempting to log in multiple times or a session not being properly terminated.
  Cause:
  
  Multiple Logins: The user is trying to log in to the same client while already being logged in.
  Session Timeout: The previous session may not have been properly closed, leading to the user being considered still logged in.
  Network Issues: Intermittent network issues may cause the system to think the user is still active.
  User Lock: The user account may be locked or restricted, preventing a new session from being established.
  
  Solution:
  
  
  Log Off Existing Session: If the user is logged in elsewhere, they should log off from that session. This can be done by:
  
  Using the transaction code SM04 (User Overview) to see active sessions and log off from there.
  If you have administrative access, you can terminate the session for the user from the same transaction.
  
  
  
  Check for Active Sessions: Use transaction SM04 or AL08 to check for active sessions and see if the user is indeed logged in. If so, you can log them off.
  
  
  Wait for Timeout: If the session is not actively being used, it may time out on its own after a certain period. You can wait for this timeout to occur.
  
  
  User Lock: If the user account is locked, the administrator should unlock the account using transaction SU01.
  
  
  Contact Support: If the issue persists, it may be necessary to contact your SAP Basis team or support for further investigation.
