Calling FF.5 through zprogram

Hi All,

I have a requirement, according to that I have to pick file from desktop change its format and pass it on to FF.5

I have used gui_upload to pick and converted the file in an itab. Now how do I pass this itab to FF.5 in my zprogram?

I  tried

  Submit RFEBKA00

    WITH

     SELECTION-TABLE iout

      and return

But this gives me a dump. PERFORM PARAMETER TOO SHORT.

Any help please.

Thanks!
