• What is the cause and solution for SAP error message 00134 - Maximum number of sessions reached ?

  The SAP error message "00134 Maximum number of sessions reached" indicates that the maximum number of user sessions allowed for a particular user or for the entire SAP system has been reached. This can occur in various scenarios, such as when a user tries to log in while already having the maximum number of active sessions open.
  Causes:
  
  User Session Limit: Each user has a limit on the number of concurrent sessions they can open. This limit is defined in the user profile settings.
  System-Wide Session Limit: The SAP system itself has a maximum number of sessions that can be active at any given time, which is defined in the system parameters.
  Unclosed Sessions: Users may have left sessions open without logging out properly, leading to the maximum session limit being reached.
  Configuration Settings: The configuration settings for user sessions may not be optimized for the number of users accessing the system.
  
  Solutions:
  
  Log Out of Existing Sessions: The user should log out of any existing sessions that are no longer needed. This can be done by closing the browser or using the log-off option in the SAP GUI.
  Increase User Session Limit: If appropriate, an administrator can increase the maximum number of sessions allowed for the user in their user profile. This can be done in transaction code SU01 (User Maintenance).
  
  Go to the "Parameters" tab and adjust the parameter z2 (maximum number of sessions).
  
  
  Increase System-Wide Session Limit: If the issue is affecting multiple users, the system-wide session limit may need to be increased. This can be done by adjusting the profile parameters in the instance profile (e.g., rdisp/max_wprun_time).
  Session Management: Implement better session management practices, such as regularly monitoring active sessions and ensuring users log out when they are done.
  Check for Background Jobs: Sometimes, background jobs may consume sessions. Ensure that background jobs are not using up the available sessions.
