Identifies the session (Progress.BPM.UserSession) associated with a connection made to a Business Process Server on behalf of a specific user. The Business Process Server generates a unique session ID each time a user connects to it. This session ID is then assigned to the SessionId property on the connected UserSession object. This SessionId property has the Unknown value (?) if there is no current connection (if the Connect( ) method has not run successfully, or if Disconnect( ) has been called).
