When you run a service, Designer invokes the service (just as an ordinary IS client would) and receives its results. The service executes once, from beginning to end (or until an error condition forces it to stop). The service executes on the Integration Server on which you have an open session, or if you using a launch configuration, on the Integration Server specified in the launch configuration.

Results from the service are returned to Designer and displayed in Results view. This allows you to quickly examine the data that the service produces and optionally change it or save it to a file. You can use the saved data as input for a later debug session or to populate the pipeline during a debugging session.
