• What is the cause and solution for SAP error message LQ389 - Maximum number of sessions reached; close an application ?

  The SAP error message LQ389: Maximum number of sessions reached; close an application typically occurs when a user has reached the maximum number of allowed sessions in the SAP system. Each user can have multiple sessions open simultaneously, but there is a limit set by the system configuration.
  Cause:
  
  Session Limit Reached: Each user has a predefined limit on the number of sessions they can open. This limit is set in the SAP system profile parameters.
  Open Sessions: The user may have multiple SAP GUI windows or sessions open, which collectively exceed the allowed limit.
  System Configuration: The system may be configured to restrict the number of sessions for performance or security reasons.
  
  Solution:
  
  
  Close Unused Sessions: The simplest solution is to close any unnecessary SAP sessions. You can do this by:
  
  Closing the SAP GUI windows that you are not actively using.
  Logging off from sessions that are no longer needed.
  
  
  
  Check Current Sessions: You can check how many sessions you currently have open by using the transaction code SM04 (User Overview) or AL08 (Global User Overview) to see your active sessions.
  
  
  Increase Session Limit: If you frequently need more sessions, you can request an increase in the session limit from your SAP Basis administrator. This involves changing the profile parameter rdisp/mshm_max_sessions or rdisp/gui_auto_logout in the system configuration.
  
  
  Log Off Inactive Sessions: If you have sessions that are inactive for a long time, you can log them off to free up space for new sessions.
  
  
  User Profile Settings: Check your user profile settings to see if there are any restrictions on the number of sessions you can open.
  
  
  Related Information:
  
  SAP Notes: You can search for relevant SAP Notes in the SAP Support Portal for more detailed guidance or specific configurations related to session limits.
  Transaction Codes: Familiarize yourself with transaction codes like SM04, AL08, and SU01 (User Maintenance) to manage user sessions and profiles effectively.
  Performance Considerations: Keep in mind that having too many sessions open can impact system performance, so it's best to only open the sessions you need.
