Changing the Selection Screen on the selection of a radio button

Question

Hi experts,
I am stuck with a situation here.
I have a selection screen with 2 blocks.
The first block contains 5 radio buttons.
The second block contains 7 select options fields.
Now i want to show different select options when the user selects different radio buttons.
For example, when the user selects radio button 1, select options 1, 2, 3, 4,  and 5 should be shown.
When the user selects radio button2,  select options 3, 4, 5, 6, and 7 should be shown.
How do i go about implementing this????
I guess i need to do the coding in event "AT SELECTION-SCREEN OUTPUT".
Should i use MODIF ID????
Please help.
Points will be awarded.
Thanks and Regards

Answer 1

Use AT SELECTION-SCREEN  
not AT SELECTION-SCREEN OUTPUT.
cause output addition makes it a PBO not PAI
check ur requirement & use the events accordingly
group all select options under one group which you want to show on selection of radio button
under AT SELECTION-SCREEN   
loop at screen and change the property "ACTIVE (0/1)" for the group you want
& don't forget to modify screen table in the end.
one more thing u should do is use addition USER-COMMAND with your radio buttons.
PARAMETERS : r1 RADIOBUTTON GROUP r1 USER-COMMAND f1,
             r2 RADIOBUTTON GROUP r1.
PARAMETERS : p1 TYPE c MODIF ID a,
             p2 TYPE c MODIF ID b.
AT SELECTION-SCREEN . " output
  LOOP AT SCREEN .
    IF r2 = 'X' AND screen-name = 'P1'.
      screen-active = '0'.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.
