Multiple records with select option

Question

i have to use select option in selection screen, which wl take the multiple values but that select option wont act as a range, the select option is a session name  from sm35, the table from where data is retrieved is APQI, i have used  a parameter before using select option ,like:
selection-screen begin of line.
parameters: P_grpid like apqi-groupid.
select-options: s_grpid like apqi-groupid.
selection-screen end of line.
AT-SELECTION SCREEN ON VALUE REQUEST FOR p-GRPID. " previous situation
{the code starts
FM F4 selection is called}
AT-SELECTION SCREEN ON VALUE REQUEST FOR S_GRPID-low. " CURRENT situation
FM F4 selection is called}
now when i give data in slection screen for s_grpid-low then it works as a parametr, but it doesnt take multiple values at s_grpid when i have alos mentioned the same for s_grpid-high.
Please tell me how to achive multiple records with select option, or u can also send a sample code if you have..
Thanks

Hello Swarnali,
You need to fill internal table of select-option once you got into the event AT SELECTION-SCREEN ON VALUE REQUEST FOR so_carr-LOW.
so sudo code will be:
AT SELECTION-SCREEN ON VALUE REQUEST FOR so_carr-LOW.
Select data from table.
   so_carr-LOW = value
   append so_carr.
You can also use NO INTERVAL to suppress the so_carr-HIGH value on selection screen.
Thanks,
Augustin.
