listbox

Former Member — Tue, 07 Mar 2006 06:47:54 GMT

When i select a value in a listbox,the values related to the selected value must be displayed in another listbox.

I am getting the values but only after pressing the enter key.i want the values without pressing the enter key.

Use user-command field to trigger an event when the listbox is selected. See a sample 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<b> USER-COMMAND fcodex.</b>
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.
<b>  if sy-ucomm eq 'FCODEX'.</b>
    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.
    <b>IF SY-UCOMM NE 'FCODEX' OR SY-UCOMM NE 'FCODEY'.</b>      CALL FUNCTION 'VRM_SET_VALUES'
        EXPORTING
          ID     = NAME
          VALUES = LIST.
      MODIFY SCREEN.
    ENDIF.
  ENDLOOP.

START-OF-SELECTION.
  clear i_spfli.
  refresh i_spfli.
select * into table i_spfli from spfli where carrid = ps_parm and connid
 = pq_param.

  loop at i_spfli.
    WRITE: / 'CITY FROM:', I_SPFLI-CITYFROM, 'CITY TO :',I_SPFLI-CITYTO,
   'DEPARTURE TIME :', I_SPFLI-DEPTIME.
  ENDLOOP.

hi Suganya,

sample on your requirement

data: i_spfli type spfli occurs 0 with header line.


PARAMETERS PQ_PARAM LIKE SPFLI-connid AS LISTBOX VISIBLE LENGTH 15
USER-COMMAND
fcodey.
*DS AS CHECKBOX USER-COMMAND FLAG.

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.

if u want values in the screen to be read with out pressing enter,

use the fn module

DYNPRO_READ_VALUES or DYNPRO_FIELD_GET WHICH WILL READ THE VALUES IN THE SCREEN

Hi,

if you choose it from drop down you will get it,

But i don't know how you are doing, can you tell me..

it should be like this..

in PAI flow logic

PROCESS AFTER INPUT.
 MODULE USER_COMMAND_0110.

PROCESS ON VALUE-REQUEST.
  FIELD: v_drop MODULE get_dropdown.

MODULE GET_DROPDOWN INPUT.
* populate listbox
  NAME = 'V_DROP'.
  CALL FUNCTION 'VRM_SET_VALUES'
    EXPORTING
      ID     = NAME
      VALUES = LIST.
ENDMODULE.                 " get_dropdown  INPUT

Hi,

Have you tried Wenceslaus G's code?It's working fine.

Re: listbox

Former Member — Tue, 07 Mar 2006 09:10:36 GMT

Hi Suganya,

I suppose your requirement is when you click on a particular value, a new screen with another listbox should appear. This is how it works.

Consider a listbox whose function code is defined as LIST. The listbox name is MARA-MTART. so at runtime the list box will be populated with MTART values.

In the PAI event. do the following.

case sy-ucomm.

when 'LIST'.

call screen '200'.

endcase.

In the screen 200, you define another listbox with some other values.

This should work.

Sylendra.
