Hi,

You can write your code for both LOW and HIGH as follows

AT SELECTION-SCREEN ON selcrit-low.

You can check here if the value is 'A'

AT SELECTION-SCREEN ON selcrit-high.

You can check here if the value is 'D'.

Alternatively you can check as follows:

If 'A' in selcrit AND 'B' in selcrit AND 'C' in selcrit AND 'D' in selcrit.

endif.

Hi,

Check the code below:

AT SELECTION-SCREEN.

• To validate the selection screen

PERFORM validate_selection_screen.

• check_vendor .

CLEAR: gs_lfa1.

IF NOT pa_lifnr IS INITIAL.

SELECT lifnr

INTO gs_lfa1

UP TO 1 ROWS

FROM lfa1

WHERE lifnr EQ pa_lifnr.

ENDSELECT.

IF sy-subrc NE gc_zero_num.

MESSAGE i000. "Enter Valid Vendor Number

ENDIF.

ENDIF.
