thank you. The appintegrator iview did work. And this will let me have just very few iviews and they can pass in the webdynpro screen as a parameter.
The downside, as compared to just the URL iview, is I could not see how to externalize the system portion of the URL, so that it would automatically be updated as transported from D to Q to P, but that is easy to fix in each landscape in this type.
