Giulio if scripting is enabled on both sides then it should work. And I'm assuming you're using SAP thick-client, not a web app. Because there might be custom elements types we've never seen before, it's not guaranteed that the spy mode will pick everything up, but it should see the basics like buttons, field, dropdowns, tables etc. Does the spy mode pick up simple elements or nothing at all? If it's nothing at all then there must be something wrong. In my experience the exe top attach to is called saplogon.
