Hi Srinivas,

Sample code,

PARAMETERS : p_carr(2) TYPE c.

DATA: BEGIN OF fs_sflight OCCURS 0,

carrid TYPE dfies-fieldname,

END OF fs_sflight.

DATA : r_carr TYPE TABLE OF ddshretval WITH HEADER LINE.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR p_carr.

APPEND 'AA' TO fs_sflight.

APPEND 'LH' TO fs_sflight.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'CARRID'

dynpprog = sy-repid

dynpnr = '1000'

dynprofield = 'P_CARR'

window_title = 'carrier'

value_org = 'S'

TABLES

value_tab = fs_sflight[]

return_tab = r_carr[].

This event is fired when the user hits F4 on the field. This is used to provide F4 Help for the field. Here is a sample program.

code

report zrich_0001 .

tables: t001.

data: begin of it001 occurs 0,

bukrs type t001-bukrs,

butxt type t001-butxt,

ort01 type t001-ort01,

land1 type t001-land1,

end of it001.

select-options s_bukrs for t001-bukrs.

initialization.

select bukrs butxt ort01 land1 into table it001 from t001.

at selection-screen on value-request for s_bukrs-low.

call function 'F4IF_INT_TABLE_VALUE_REQUEST'

exporting

retfield = 'BUKRS'

dynprofield = 'S_BUKRS'

dynpprog = sy-cprog
