Hi,

you need to use AT SELECTION-SCREEN ON FILED_NAME event.

data : so_ekpo for matnr-ekpo.

at selection-screen on so_ekpo.

Hi Paramabap,

Put this code in the at selection-screen event......

as mentioned in above thread....

Select field 1

field2

into itab

from table

where ekpo = so_ekpo.

If sy-subrc <> 0.

Give error

Endif.

Likekewise....

depends upon the requirement whether its necessary to fill all the fields or not...

Hi,

using AT SELECTION SCREEN Event screen validations can be done.

DATA: sflight_tab TYPE TABLE OF sflight,

sflight_wa LIKE LINE OF sflight_tab.

• Selection screens

PARAMETERS p_carrid TYPE spfli-carrid.

SELECTION-SCREEN BEGIN OF SCREEN 500.

SELECT-OPTIONS s_conn FOR sflight_wa-connid.

DATA s_conn_wa LIKE LINE OF s_conn.

SELECTION-SCREEN END OF SCREEN 500.

• Handling selection screen events

AT SELECTION-SCREEN ON p_carrid.

IF p_carrid IS INITIAL.

MESSAGE 'Please enter a value' TYPE 'E'.

ENDIF.

Thanks,

Nelson
