Datawindow saveas() for a single page

I have a data window which has multiple pages in it. Requirement is to save the file with first page (only one page) onto a database table.

But when I try with saveas it saves complete datawindow (all pages).

Is there a way to save only first page (or n th page) of a datawindow to a file ?

Appreciate your help!

Thanks,
