F4 HELP IN SELECTION SCREEN

Former Member — Mon, 28 Apr 2008 09:52:35 GMT

In selection screen I have TWO Fields Plant and Material No.

If I input Plant, how do I get the Material No: based on the Plant dynamically?

You have to use the function module DYNP_VALUES_READ to read the selection screen data after u enter the field value in Plant . Based on that, then call the function module F4_INT_VALUE_REQUEST. And this function module will

retrive based on the value enter on the field1.

Have a look at below sample code:

If you have two parameters, you want to display values(f4) in parameter 2 depending on the values entered in parameter 1.

REPORT Z_SRI_HELP_VALUE_FOR_TABLES .

tables tcurt.

DATA DYFIELDS LIKE DYNPREAD OCCURS 1 WITH HEADER LINE.

PARAMETERS: P_WAERS LIKE TCURT-WAERS, "Currency

P_LTEXT LIKE TCURT-LTEXT, "Long Text

P_KTEXT LIKE TCURT-KTEXT. "Short Text

Example of updating value of another field on the screen

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_WAERS.

CLEAR: DYFIELDS[], DYFIELDS.

*select currency

CALL FUNCTION 'HELP_VALUES_GET'

EXPORTING

fieldname = 'WAERS'

tabname = 'TCURT'

IMPORTING

SELECT_VALUE = P_WAERS.

get long text for the selected currency

SELECT SINGLE LTEXT FROM TCURT

INTO DYFIELDS-FIELDVALUE

WHERE SPRAS = SY-LANGU

AND WAERS = P_WAERS.

IF SY-SUBRC <> 0.

CLEAR DYFIELDS-FIELDVALUE.

ENDIF.

update another field

DYFIELDS-FIELDNAME = 'P_LTEXT'.

APPEND DYFIELDS.

CALL FUNCTION 'DYNP_VALUES_UPDATE'

EXPORTING

DYNAME = SY-CPROG

DYNUMB = SY-DYNNR

tables

dynpfields = DYFIELDS .

Example of reading value of another field

AT SELECTION-SCREEN ON VALUE-REQUEST FOR P_KTEXT.

*read another field

CLEAR: DYFIELDS[], DYFIELDS.

DYFIELDS-FIELDNAME = 'P_WAERS'.

APPEND DYFIELDS.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = SY-CPROG

DYNUMB = SY-DYNNR

TABLES

DYNPFIELDS = DYFIELDS .

READ TABLE DYFIELDS INDEX 1.

get short text and update current field

SELECT SINGLE KTEXT FROM TCURT

INTO P_KTEXT

WHERE SPRAS EQ SY-LANGU

AND WAERS EQ DYFIELDS-FIELDVALUE.

Hope this will solve the problem.

Thanks,

Hi,

Use the below logic.

tables: t001k.

For Identification Number

DATA: BEGIN OF it_bwkey OCCURS 0,

bwkey LIKE t001k-bwkey,

END OF it_bwkey.

data: v_bukrs(4).

For Run date

DATA: BEGIN OF it_bukrs OCCURS 0,

bukrs LIKE t001k-bukrs,

END OF it_bukrs.

DATA it_ret LIKE ddshretval OCCURS 0 WITH HEADER LINE.

SELECTION-SCREEN: BEGIN OF BLOCK main WITH FRAME TITLE text-001.

SELECTION-SCREEN SKIP.

PARAMETERS: p_bukrs(4) TYPE c.

SELECT-OPTIONS s_bwkey FOR t001k-bwkey NO INTERVALS.

SELECTION-SCREEN END OF BLOCK main.

You read the values using FM DYNP_VALUES_READ. The value of plant that you have got from this should be used in the select statement to get values of material in where clause. Pass that internal table to FM F4IF_INT_TABLE_VALUE_REQUEST.

Have a look at below code snippet.

CALL FUNCTION 'DYNP_VALUES_READ'

EXPORTING

DYNAME = PROGNAME

DYNUMB = DYNNUM

TRANSLATE_TO_UPPER = 'X'

TABLES

DYNPFIELDS = DYNPRO_VALUES.

READ TABLE DYNPRO_VALUES INDEX 1 INTO FIELD_VALUE.

SELECT CARRID CONNID

FROM SPFLI

INTO CORRESPONDING FIELDS OF TABLE VALUES_TAB

WHERE CARRID = FIELD_VALUE-FIELDVALUE.

CALL FUNCTION 'F4IF_INT_TABLE_VALUE_REQUEST'

EXPORTING

RETFIELD = 'CONNID'

DYNPPROG = PROGNAME

DYNPNR = DYNNUM

DYNPROFIELD = 'CONNECTION'

VALUE_ORG = 'S'

TABLES

VALUE_TAB = VALUES_TAB.

I hope it helps.

Thanks,

Vibha
