For example, look at this code

=====================================================

TABLES : MARD.

DATA: BEGIN OF IT_MARD OCCURS 0,

WERKS LIKE MARD-WERKS,

LGORT LIKE MARD-LGORT,

END OF IT_MARD.

DATA : T_RETURN TYPE STANDARD TABLE OF DDSHRETVAL WITH HEADER LINE.

parameters : P_WERKS LIKE MARD-WERKS.

parameters : P_LGORT LIKE MARD-LGORT.

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_WERKS.

SELECT WERKS LGORT FROM MARD UP TO 10 ROWS INTO table IT_MARD.

DELETE ADJACENT DUPLICATES FROM IT_MARD COMPARING WERKS.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'WERKS'

DYNPPROG = SY-REPID

DYNPNR = '1000'

DYNPROFIELD = 'P_WERKS'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = IT_MARD

RETURN_TAB = T_RETURN

EXCEPTIONS

PARAMETER_ERROR = 1

NO_VALUES_FOUND = 2

OTHERS = 3.

if sy-subrc = 0.

read table it_mard index 1. "transporting werks.

move it_mard-lgort to p_lgort.

endif.

Hi,

Its easy.

1. if your parameter is like some system field or standard table field use like stmt .F4 will automaticaly come.

tables : vbak.

parameters: s like sy-datum,

v like vbak-vbeln.

2. else create a match-code object in se11 and use following stmnt

SELECT-OPTIONS <sel-opt name> FOR <fieldname> MATCHCODE OBJECT <match-code obj nam>.

Sumit.

hi friends

thanx for the reply

but it need to take data from a table.

thanx

Re: f4 help

Former Member — Mon, 24 Jul 2006 11:29:11 GMT

Hi Sandeep,

Just check my code.It is taking the data from the database table MARA to an internal tabel after that i am passing that internal table to the FM.

There is not any FM in which you can pass the database table directly.

Hi Sandeep,

Create a search (in DDIC/SE11) and Check Import and Export Checkbox in that search. Give the Table name and field which has the value (Table that has the Value for that field). Then Assign this search help to the field in the Database table. Use the Database field assigned with this for the Field in your Program.

Hope this would help you!

Hi Kishan,

Thank you so much for the code, it really helped me when i was trying to create function module for HR position with the sales org and couldn't find a way to link it to F4. But the sample code you had in the blog really helped me.

Thanks a lot ..
