• What is the cause and solution for SAP error message BCOMEC019 - The maximum permitted number of users logged on has been reached ?

  The SAP error message BCOMEC019 indicates that the maximum number of users allowed to log on to the SAP system has been reached. This is a common issue in environments where user licenses are limited or where the system is configured to restrict the number of concurrent logins.
  Cause:
  
  License Limitations: The SAP system has a defined limit on the number of concurrent users based on the type of license purchased. If this limit is reached, new users will be unable to log in.
  Session Management: Users may not have logged out properly, leaving their sessions active and consuming available user slots.
  Configuration Settings: The system may be configured to allow a specific number of concurrent logins, which can be lower than the total number of licensed users.
  
  Solution:
  
  
  Check User Sessions:
  
  Use transaction code SM04 to view active user sessions. This will help identify if there are users who are logged in but not actively using the system.
  If necessary, you can terminate inactive sessions from this screen.
  
  
  
  Review License Usage:
  
  Check the license usage in transaction SLICENSE to see how many users are currently logged in versus the number of licenses available.
  If you are consistently hitting the limit, consider discussing with your SAP account representative about increasing your user licenses.
  
  
  
  Adjust Configuration:
  
  If the maximum number of concurrent users is set too low, you may need to adjust the configuration settings in the SAP system. This can typically be done in the RZ10 transaction by modifying the instance profile parameters related to user sessions.
  
  
  
  User Management:
  
  Encourage users to log out when they are finished using the system to free up slots for others.
  Implement policies for session timeouts if users are inactive for a certain period.
  
  
  
  System Monitoring:
  
  Regularly monitor user activity and system performance to ensure that you are not frequently hitting the user limit.
  
  
  
  Related Information:
  
  SAP Notes: Check SAP Notes related to user management and licensing for any specific recommendations or updates.
  Documentation: Review the SAP documentation for your specific version to understand user management and licensing better.
  Support: If the issue persists, consider reaching out to SAP support for assistance, especially if you believe there is a discrepancy in the number of licenses or if you need help with configuration changes.
  
  By following these steps, you should be able to resolve the BCOMEC019 error and manage user sessions more effectively in your SAP environment.
