  The SAP error message SHTTP030: Could not create new session typically indicates an issue with the HTTP session management in the SAP system. This error can occur in various scenarios, particularly when dealing with SAP Web Application Server (WAS) or when using SAP's Internet Communication Framework (ICF).
  Causes:
  
  Session Limit Reached: The maximum number of sessions allowed for the user or the system may have been reached.
  Configuration Issues: Incorrect configuration settings in the SAP system or the web server can lead to session creation failures.
  Network Issues: Problems with network connectivity or firewalls may prevent the session from being established.
