Hi,

Check the following code:

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.

Regards,

Bhaskar

Hi,


PARAMETERS p TYPE spfli-carrid AS LISTBOX VISIBLE LENGTH 20.

Please look at the documentation below from ABAPDOCU.

... AS LISTBOX

Effect

Generates a dropdown list box for the parameter p input field on the selection screen. If the parameter is created with a data type from the ABAP Dictionary and the data type is linked with an input help from the ABAP Dictionary, the system displays the first input help column in the list box.

Note

You must always specify the VISIBLE LENGTH addition with the AS LISTBOX addition, to define a suitable list box width for the input help.

Example

PARAMETERS p TYPE spfli-carrid AS LISTBOX VISIBLE LENGTH 20.

Addition 23

... USER-COMMAND ucom

Effect

This addition is only supported for parameters that are defined as checkboxes or radio buttons. In this case, clicking the parameter triggers the user command ucom, similarly to SELECTION-SCREEN PUSHBUTTON.

Notes

Since all parameters of a radio button group have the same user command, you can only use this addition with the first parameter in the group. The user command is then triggered when you click any button in the group.

If the parameter does not have the RADIOBUTTON GROUP or AS CHECKBOX addition, it must have type Character and length 1. It is then displayed as a checkbox.
