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.

Message is showing after returning from list screen....i want to show the message before output...then user select a check box... then execute the code(F8)

[SharathYaralkattimath]

Replace

AT SELECTION-SCREEN OUTPUT.

with

AT SELECTION-SCREEN.

...........

message 'xxxxx' type 'E'.

.............

[jyotirmaya_mallick]

by using AT SELECTION-SCREEN.... message is showing in list screen...not on the selection screen

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'.

>there should 2 check box....user can select both or AT least one

>if user doesnt select any check box...a message should display to select at leaste one

>message should show when user click execute(F8) without any checkbox selected...

AT SELECTION-SCREEN.

IF p_cb1 is INITIAL and p_cb2 IS INITIAL.

IF sy-ucomm = 'ONLI'. " When user presses F8

* Give your error message

ENDIF.

ENDIF.
