Hi...

2 ways...

1 )AT SELECTION-SCREEN. u can do the validation...and put MESSAGE E000(00) with text.

2) or in START-OF SELECTION ....do the validation..if not satisfies..

if field is not initial..

v_flg = 'X'.

MESSAGE S000(00) with text.

STOP.

endif.

CHECK v_flg <> 'X'.

do the rest of the coding....

You use at selection-screen event.

in event do required validations on fileds and display error message accordingly.

Use at selection screen

use perform inside it on the field you want like the sample code below:

AT SELECTION-SCREEN.

*Validate Sales Organization.

AT SELECTION-SCREEN ON s_vkorg.

PERFORM vkorg_validate.

FORM vkorg_validate .

DATA: lv_vkorg TYPE vbak-vkorg.

SELECT SINGLE vkorg

FROM tvko

INTO lv_vkorg

WHERE vkorg EQ s_vkorg-low.

IF sy-subrc NE 0.

MESSAGE e100 DISPLAY LIKE 'I'. "Please enter valid Sales Organization.

similarly you can do for other fields too.

Hope it helps.
