Selection-screen(condition)

Question

Hi all,
I have a report with about 15 select-options in selection screen. My condition is there should be atleast one input from the end user if not I should say 'Not enough inputs'. For this I implemented a logic using 'at selection-screen' event. It is working well.
My question is when I execute my report, I see the Multiple selections option (right arrow button) for all the select-options in the selection screen. When I press this button, I am not getting a pop-up but the condition which I kept in 'at selection-screen' event is executed and it says 'no enough inputs'.
When I press the Multiple selections button the control is passing through the 'at selection-screen' event. Is it possible that when I press the Multiple selections button, I get the pop-up before the control comes to 'at selection-screen' event.
Below is my code. Please try this code for example.
select-options:    s_werk    for qals-werk.
select-options:    s_matnr   for qals-matnr  matchcode object mat1.
select-options:    s_charg   for qals-charg  matchcode object mch1.
select-options:    s_art     for qals-art.
select-options:    s_pruef   for qals-prueflos.
select-options:    s_vaplz   for aufk-vaplz.
select-options:    s_ltxa1   for afvc-ltxa1.
select-options:    s_aufnr   for qals-aufnr.
select-options:    s_enst    for qals-enstehdat.
select-options:    s_past    for qals-pastrterm.
select-options:    s_paend   for qals-paendterm.
select-options:    s_plnty   for qals-plnty.
select-options:    s_herst   for qals-hersteller matchcode object kred.
select-options:    s_lifnr   for qals-lifnr  matchcode object kred.
select-options:    s_kunnr   for qals-kunnr  matchcode object debi.
select-options:    s_verwm   for qamv-verwmerkm.

if  s_art[] is initial and
if  s_pruef[] is initial and
if  s_vaplz[] is initial and
