The copy/paste does what you need to copy objects from a qvw to another.
However for the data, you either need to have the same reload script in the 2nd qvw, or you can read the 1st qvw as binary.
You do this from the edit script window (ctrl+e), in the bottom click on "Qlikview file" and select your source file. You'll have something like this at the beginning of your script:
And after reloading your 2nd qvw, you'll have same data as in your 1st qvw.
Hope this helps.
