Calling subscreen on click of radio button

Question

Hi,
I am creating a module pool program , in which on click of a radio butto to 'YES' a subscreen should appear ( on the main screen) with few fields so that the user can input values of it.
But I am having proble in calling the subscreen in PAI event.Actually I think it should be something like this
Module user_command.
  case sy-ucomm.
   when rb_yes = 'X'
    { CALL SUBSCRREN CODE
ENDIF.
Can this be done? I f yes how? I only know how to call subscreen in PBO, but the syntax for calling subscrren is different in PAI i think.

Hi,
Try doing this.
This is your flow logic in the main screen  to call the Subscreen's PBO
PROCESS BEFORE OUTPUT.
MODULE STATUS_0110.
CALL SUBSCREEN TAB1_REF1 INCLUDING 'ZTRIAL' '0111'.
In the PAI of the main screen,
PROCESS AFTER INPUT.
MODULE USER_COMMAND_0110.
CALL SUBSCREEN TAB1_REF1.
Assign a function code to your radio button.
Layout -> Attributes -> Function Code
In the TOP include,
DATA: v_dynnr type sy-dynnr.
In module USER_COMMAND_0110.
if p_rad = 'X'.
   v_dynnr = '0111'.
else.
  v_dynnr =  ' '
endif.
