REPORT ZEX_DROPDOWN_LIST MESSAGE-ID ZGENERAL.

TABLES SPFLI.

DATA: BEGIN OF ITAB OCCURS 0,

CARRID LIKE SPFLI-CARRID,

CONNID LIKE SPFLI-CONNID,

END OF ITAB.

DATA ok_code TYPE sy-ucomm.

START-OF-SELECTION.

CALL SCREEN 0200.

Hi,

Please refer to the code below:

REPORT ZLIST.

TYPE-POOLS: VRM.

DATA: NAME TYPE VRM_ID,

LIST TYPE VRM_VALUES,

VALUE LIKE LINE OF LIST.

PARAMETERS: PS_PARM(10) AS LISTBOX VISIBLE LENGTH 10.

AT SELECTION-SCREEN OUTPUT.

NAME = 'PS_PARM'.

VALUE-KEY = '1'.

VALUE-TEXT = 'LINE 1'.

APPEND VALUE TO LIST. VALUE-KEY = '2'.

VALUE-TEXT = 'LINE 2'.

APPEND VALUE TO LIST.

CALL FUNCTION 'VRM_SET_VALUES' EXPORTING ID = NAME VALUES = LIST.

START-OF-SELECTION.

WRITE: / 'PARAMETER:', PS_PARM.

Hope it is useful.

Thanks,

Sandeep.

Hi

You have given it incorrectly. The FM needs to be called at 'PROCESS ON VALUE-REQUEST' in the flow logic of that screen:

PROCESS ON VALUE-REQUEST

FIELD <field-name for which f4 help req> MODULE <module_name>

Now call the FM in the module <module_name>

Thanks

Vijay
