Dropdown list box in selection screen

[Former Member]

Hello Expert,

I am creating a selection screen wherein I have to use drop-down list box for 3 fields. I want to get the current field on which the cursor is placed so that its drop down list will be displayed.I tried it using USER-COMMAND fcode option with parameters statement. But the control doesn't go to the AT SELECTION-SCREEN event when we click on a field for displaying its drop down.

How can I get the current parameter to display its dropdown?

Please help.Its urgent.

Hi Radhika,

Check the below code, this might get you the solution.

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.

Use the function module VRM_SET_VALUES to link a field on screen to a drop list.

Sample

* Parameter with listbox
  PARAMETERS: pdfopt AS LISTBOX VISIBLE LENGTH 30 MODIF ID pdf.

* Filling the list box
AT SELECTION-SCREEN OUTPUT.

  DATA: vrm_id TYPE vrm_id,
        vrm_values TYPE vrm_values,
        vrm_value LIKE LINE OF vrm_values.

  CLEAR vrm_value.
  APPEND vrm_value TO vrm_values.

  vrm_value-key = 'D'.
  vrm_value-text = text-100.
  APPEND vrm_value TO vrm_values.

  vrm_value-key = 'S'.
  vrm_value-text = text-101.
  APPEND vrm_value TO vrm_values.

  vrm_id = 'PDFOPT'.

  CALL FUNCTION 'VRM_SET_VALUES'
       EXPORTING
            id              = vrm_id
            values          = vrm_values
       EXCEPTIONS
            id_illegavrm_id = 1
            OTHERS          = 2.
  IF sy-subrc <> 0.
    MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
    WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
  ENDIF.

Hi,

The list box is to be filled for 3 parameters on selection screen.

When the user clicks on the parameter, that should be dynamically stored in a variable which then I will pass to the function module to display the list box.

[RaymondGiuseppi]

I don't know if it is possible, dropdown list must (<i>as far as I know</i>) be ready before sending the screen (in PBO)

You can use F4IF_INT_TABLE_VALUE_REQUEST in the AT SELECTION-SCREEN ON VALUE-REQUEST FOR (PROCESS ON VALUE-REQUEST) reading some values from the dynpro (DYNP_VALUES_READ) but i don't know a way to display the list in a dropdown list at this stage, in this function module.

With my opinion, you should to fill the three list box in initialization or PBO.

2.

REPORT abc.

DATA : v TYPE vrm_values.

DATA : vw LIKE LINE OF v.

PARAMETERS : a(10) TYPE c AS LISTBOX VISIBLE LENGTH 10.

INITIALIZATION.

vw-key = '1'.

vw-text = 'Jan'.

APPEND vw TO v.

vw-key = '2'.

vw-text = 'Feb'.

APPEND vw TO v.

vw-key = '3'.

vw-text = 'Mar'.

APPEND vw TO v.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = 'A'

values = v
