  The SAP error message "14027 Maximum number of GUI sessions reached" indicates that a user has reached the maximum number of concurrent GUI sessions allowed for their user account in the SAP system. This limit is set by the system administrator to manage resources and ensure system performance.
  Cause:
  
  Session Limit Reached: Each user has a predefined limit on the number of active GUI sessions they can have open simultaneously. This limit is configured in the SAP system.
  Unclosed Sessions: Users may have multiple sessions open and may not have closed previous sessions properly.
  Configuration Settings: The maximum number of sessions can be set in the user profile or system-wide settings.
  
  Solution:
  
  Close Unused Sessions: Check if there are any open sessions that can be closed. You can do this by navigating through the SAP GUI and closing any unnecessary windows.
  Log Off: If you are unable to close sessions, logging off from the SAP system will terminate all active sessions for your user account.

  Accessing transaction code SU01 (User Maintenance).
  Entering your user ID and clicking on the "Change" button.
  Navigating to the "Parameters" tab and adjusting the parameter ztta/roll_area or rdisp/gui_auto_logout as needed.
