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).
