Dropdown list in selection screen

[Former Member]

Hi Experts,

Can any one say how to create a dropdown list in a report's selection screen and how to populate values on that? I searched in SDN, but most of the hits were for module pool only.

Thanks and regards,

Venkat.

Hi,

You can give dropdown list in selection-screen via PARAMETERS

PARAMETERS p_name(n) AS LISTBOX .

Also addition

PARAMETERS p_name(n) AS LISTBOX VISIBLE LENGTH n.(can be added)

where n is an integer .

To populate the value list use the Function module VRM_SET_VALUES .

and place it in atselection-screeen output event.

Hi,

Try this

Parameter p_carr type spfli-carrid as listbox.

If u want any custom field values,create a domain with value range and create data element and use
