Thanks a lot Maxim,
these are pretty good FM's, but actually I'm just trying to replicate the single pop up screen functionality, I mean just choosing the document functionality popup screen, that's because I have a Z module pool that will do the other needed stuff, but user requested to include the popup window as it is on VA01 for "create with Reference" and I thought maybe it was wrapped as a FM popup screen and returns document number selected by user.
Regards,
Julio
