• What is the cause and solution for SAP error message RT793 - Number of user sessions by type ?

  The SAP error message RT793 indicates that the number of user sessions has exceeded the allowed limit for a specific type of user session. This can occur in various scenarios, such as when too many users are logged in simultaneously or when a single user has opened multiple sessions.
  Cause:
  
  Exceeded Session Limit: Each user type (dialog, background, etc.) has a predefined limit for the number of concurrent sessions. If this limit is exceeded, the RT793 error will be triggered.
  Configuration Settings: The system configuration may not be set up to accommodate the number of users or sessions required for your business processes.
  User Behavior: Users may be opening too many sessions without logging off from previous ones, leading to session exhaustion.
  
  Solution:
  
  Check User Sessions: Use transaction code SM04 to monitor active user sessions. Identify users with excessive sessions and ask them to log off from unnecessary sessions.
  Adjust Configuration: If the business needs require more sessions, consider adjusting the session limits in the system configuration:
  
  Go to transaction RZ10 to modify the instance profile parameters.
  Look for parameters like rdisp/max_user_sessions and rdisp/wp_no_dia to increase the limits.
  
  
  User Education: Educate users about the importance of logging off from sessions they are not using to free up resources.
  Session Management: Implement session management policies to limit the number of sessions a user can open concurrently.
