Hi,

code like this,

AT SELECTION-SCREEN OUTPUT.

IF p_check1 is INITIAL AND p_check2 IS INITIAL.

MESSAGE 'Either Checkbox 1 or Checkbox2 should be selected' TYPE 'S'.

ENDIF.

By selected you mean checked so internally in ABAP it contains 'X', I presume.

Not very clear what you need.

You could display it with default 'X' unless it depends on value of another field on the screen...

(never mind - Sharath has it right!)

Hi,

If your requirement is to have only one option selected at a given point of time, then u should go for RADIO BUTTON else if multiple options to be selected, then CHECK BOX.

I will give you a brief overview of the syntax of CHECK BOX

SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME.

PARAMETER: CB_DISPLAY AS CHECKBOX,

CB_DOWNLOAD AS CHECKBOX.

SELECT-SCREEN END OF BLOCK B1.

IF CB_DISPLAY = 'X'.

<CODE TO DISPLAY THE DATA FROM ON TO THE SCREEN'

ELSEIF CB_DOWNLOAD = 'X'.

CALL FUNCTION 'GUI_DOWNLOAD'.

with

AT SELECTION-SCREEN.

...........

message 'xxxxx' type 'E'.
