Is it possible to preview a smartform and simultaneously download the pdf?

Hello friends,

Is it possible to view the smartform (as in print/preview) and simultaneously download the pdf also?

I'm able to do only one of them.

if comment this statement, i'm able to view the SF directly but not able to download pdf.

LS_CONTROL_PARAMETERS-GETOTF = 'X'.

Anyone have a solution for this?
