If the Method is invoked in the context of a Session and the Session is terminated, the results of the Method’s execution cannot be returned to the Client and are discarded. This is independent of the task actually performed at the Server.
The order the operations are processed in the Server is not defined and depends on the different tasks and the internal Server logic. If a Method is contained in more than one operation, the order of the processing is undefined. If a Client requires sequential processing the Client needs separate Service calls.
