• What is the cause and solution for SAP error message CM_ICI_CCS897 - Could not open a new session ?

  The SAP error message CM_ICI_CCS897: Could not open a new session typically indicates an issue with the system's ability to establish a new session for a user or process. This can occur in various contexts, such as when trying to log in to the SAP system or when executing certain transactions.
  Causes:
  
  Session Limit Reached: The maximum number of sessions allowed for a user has been reached. Each user has a limit on how many concurrent sessions they can have.
  System Configuration: The SAP system may be configured to limit the number of sessions or connections.
  Network Issues: There may be network connectivity problems that prevent the establishment of a new session.
  User Lock: The user account may be locked or inactive, preventing new sessions from being created.
  Resource Limitations: The SAP application server may be experiencing resource constraints (e.g., memory, CPU) that prevent it from handling new sessions.
  Database Connection Issues: Problems with the database connection can also lead to session creation failures.
  
  Solutions:
  
  
  Check Session Limits:
  
  Verify the maximum number of sessions allowed for the user in the user profile settings (transaction code SU01).
  If the limit is reached, consider logging out of some existing sessions or increasing the limit if appropriate.
  
  
  
  Review System Configuration:
  
  Check the system parameters related to session management (e.g., rdisp/max_wprun_time, rdisp/wp_no, etc.) in transaction RZ10 or RZ11.
  Adjust the parameters if necessary, but ensure that changes are in line with system performance and capacity.
  
  
  
  Network Troubleshooting:
  
  Ensure that there are no network issues affecting connectivity to the SAP server.
  Check firewall settings, VPN connections, and other network configurations.
  
  
  
  User Account Status:
  
  Verify the status of the user account in transaction SU01. Ensure that the account is not locked or inactive.
  If the account is locked, unlock it and try again.
  
  
  
  Monitor System Resources:
  
  Use transaction ST02 (Buffer Monitor) and ST06 (Operating System Monitor) to check for resource bottlenecks.
  If the system is under heavy load, consider optimizing performance or scaling resources.
  
  
  
  Database Connection:
  
  Check the database connection settings and ensure that the database is up and running.
  Review logs for any database-related errors that might indicate connection issues.
