multiple_choice = 'X' in Search help Fn Module

What I am doing:

<b>1.</b>

I have a SELECT-OPTIONS

so_stat FOR tj30t-txt04

on my sel screen and I am calling the F4 help on

AT SELECTION-SCREEN ON VALUE-REQUEST FOR so_stat-low.

event which is rightly calling

F4IF_INT_TABLE_VALUE_REQUEST

function module and showing the desired F4 help.

<b>2.</b>

multiple_choice = 'X' is showing me check box against each entries in my F4 help.

<b>When I am selecting desired entries,</b>

It is populating

return_tab

table with all the entries I have selected. But its <b>not</b> filling up the range of so_stat.

So is it my resp to fill up the so_stat.
