You have to code in POV event.

PROCESS BEFORE OUTPUT.
...........................................
.........................................

PROCESS AFTER INPUT.
...........................................
.........................................

PROCESS ON VALUE-REQUEST.	
FIELD field_name MODULE module_name.

_IN ABAP PROGRAM_

MODULE module_name INPUT.

SELECT field_name FROM database_table INTO TABLT ITAB.

* Now call the Function module F4IF_FIELD_VALUE_REQUEST and pass ITAB in value_tab parameter.

ENDMODULE.

Ex:

*&---------------------------------------------------------------------*

Hi Friend,

In the specified screen code under PROCESS ON VALUE-REQUEST event,

fetch data from DDIC table (which you need for display), and use F4IF_INT_TABLE_VALUE_REQUEST.

Hope it will solve your problem.

hi,

if u want value from database then u can create search help through SE11 and attach that to that field of screen on which u want F4...

but if u want ur own value then u need to take POV event....

write like this in screen logic after PAI..

PROCESS ON VALUE-REQUEST.

FIELD ifmtp-form_type MODULE fm_drop.

MODULE fm_drop INPUT.

CLEAR ifmtp.

REFRESH ifmtp.

ifmtp-form_type = 'C'.

APPEND ifmtp.

ifmtp-form_type = 'F'.

APPEND ifmtp.

ifmtp-form_type = 'H'.

APPEND ifmtp.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

retfield = 'FORM_TYPE'

value_org = 'S'

TABLES

value_tab = ifmtp.

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. " fm_drop INPUT
