Hi ,

IF you want the search help for screen then u got to do in above event (POV).

If it is a selection screen then u got to do it in AT SELECTION-SCREEN ON VALUE-REQUEST FOR <FIELD-NAME> event.

Please find the following Eg.

Eg:

********For Screen

PROCESS ON VALUE-REQUEST.

FIELD x_zpinv-ztagn MODULE f4_ztagn.

MODULE f4_ztagn INPUT.

DATA:x_ret TYPE ddshretval,

it_ret LIKE TABLE OF x_ret.

DATA:BEGIN OF x_ztagn,

ztagn TYPE zpinv-ztagn,

END OF x_ztagn.

DATA:it_ztagn LIKE STANDARD TABLE OF x_ztagn.

CLEAR :x_ztagn, x_ret.

REFRESH:it_ztagn,it_ret.

SELECT ztagn FROM zpinv INTO TABLE it_ztagn

WHERE gjahr = w_cntdt+0(4)

AND bupem = w_cntdt+4(2)

AND werks = w_plant

AND lgort = w_sloc.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'ZTAGN'

dynpprog = sy-repid

dynpnr = sy-dynnr

dynprofield = 'X_ZPINV-ZTAGN'

value_org = 'S'

TABLES

value_tab = it_ztagn

return_tab = it_ret

EXCEPTIONS

parameter_error = 1

no_values_found = 2.

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

ENDMODULE. " f4_ztagn INPUT

***For selection screen

AT SELECTION-SCREEN ON VALUE-REQUEST FOR X_ZPINV-ZTAGN.

Copy the same code here from module f4_ztagn.

Hi Vijay ,

Why dont you use a search help there so that it will give you a list box ...

or else use the Function module VRM_GET_VALUES . In this FM pass the internal table with data and provide the screen-field name.

Code for the VRM_GET_VALUES in the PAI of the screen .and no need to do anything. I mean when u execute the screen and click on the down arrow button near the field , you will get the list of values to select . But make sure you have set the proper properties for that field ...

here are some sample programs from where you can get help :

demo_dropdown_list_box

emo_dynpro_dropdown_listbox.

I have worked on same scenerio and i know it works .

Reward if my answer is helpful ....

Thanks
