drop down box in a modulepool

Former Member — Fri, 13 Oct 2006 12:32:05 GMT

Hi,

I am creating a modulepool with a drop down box in one of the dynpros. I have managed to fill it with values using the 'VRM_SET_VALUES' function module.

The problem comes when running the modulepoool. The field displays the drop down box with the correct values, but it does not take the values I select. The first opcion is the defualt, and even though I choose a different one it does not take the change.

Is there something missing?

Thanks in advance,

Nerea.

YOu can use the program:

DEMO_DYNPRO_DROPDOWN_LISTBOX as an example.

Check with this code

TYPE-POOLS: VRM.

TABLES SPFLI.

TABLES SSCRFIELDS.

DATA flag.

DATA: NAME TYPE VRM_ID,

LIST TYPE VRM_VALUES,

VALUE LIKE LINE OF LIST.

PARAMETERS PS_PARM LIKE SPFLI-CARRID AS LISTBOX VISIBLE LENGTH 10

USER-COMMAND

fcodex.

data: i_spfli type spfli occurs 0 with header line.

PARAMETERS PQ_PARAM LIKE SPFLI-connid AS LISTBOX VISIBLE LENGTH 15

USER-COMMAND

fcodey.

INITIALIZATION.

NAME = 'PS_PARM'.

DATA T TYPE I VALUE 0.

SELECT DISTINCT carrid into corresponding fields of table i_spfli FROM

SPFLI.

loop at i_spfli.

VALUE-KEY = i_spfli-CARRID.

VALUE-TEXT = i_spfli-CARRID.

APPEND VALUE TO LIST.

endloop.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

ID = NAME

VALUES = LIST.

AT SELECTION-SCREEN.

if sy-ucomm eq 'FCODEX'.

REFRESH LIST.

CLEAR LIST.

PQ_PARAM = ' '.

NAME = 'PQ_PARAM'.

SELECT * FROM SPFLI WHERE CARRID = PS_PARM.

VALUE-KEY = SPFLI-connid.

VALUE-TEXT = SPFLI-connid.

APPEND VALUE TO LIST.

ENDSELECT.

endif.

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

IF SY-UCOMM NE 'FCODEX' OR SY-UCOMM NE 'FCODEY'.

CALL FUNCTION 'VRM_SET_VALUES'
