• What is the cause and solution for SAP error message FS630 - Maximum number of users reached ?

  The SAP error message FS630 "Maximum number of users reached" typically indicates that the system has reached its limit for concurrent user sessions. This can happen in various SAP environments, including SAP ERP, SAP S/4HANA, and others, where there is a defined maximum number of users that can be logged in at the same time.
  Cause:
  
  User Limit Reached: The most common cause is that the maximum number of concurrent users defined in the system profile has been reached.
  Licensing Issues: The number of users may be limited by the licensing agreement with SAP.
  Session Management: Users may not be logging out properly, leading to sessions remaining active and consuming user slots.
  System Configuration: The system may be configured to allow a limited number of users, which can be adjusted in the system settings.
  
  Solution:
  
  Check Active Sessions: Use transaction code SM04 to check the list of active users and their sessions. Identify any users who may be logged in but not actively using the system.
  Log Off Inactive Users: If there are inactive sessions, you can log off users from the SM04 transaction or use AL08 to see all users logged into the system and manage sessions.
  Increase User Limit: If you have the necessary permissions, you can increase the maximum number of users allowed in the system profile. This typically involves:
  
  Accessing the instance profile via transaction RZ10.
  Modifying the parameter rdisp/mshost or rdisp/max_user to allow more users.
  Restarting the instance for changes to take effect.
  
  
  Review Licensing: Ensure that your SAP licensing allows for the number of concurrent users you need. If necessary, contact your SAP account representative to discuss licensing options.
  Session Timeout Settings: Consider adjusting session timeout settings to automatically log off users who are inactive for a certain period, freeing up user slots.
  
  Related Information:
  
  SAP Notes: Check SAP Notes for any specific guidance or patches related to user management and session handling.
  Documentation: Review SAP documentation regarding user management and system configuration for best practices.
  Monitoring Tools: Utilize SAP monitoring tools to keep track of user sessions and system performance, which can help in managing user load effectively.
