ALV OBJECT : get selected datas

Former Member — Mon, 19 Feb 2007 09:04:46 GMT

Hello,

I built two alv in a same screen of a transaction

First I want to add a command for each line of the first screen in order to select one or severals lines pushing CTRL.(same with REUSE_ALV_GRID_DISPLAY )

With default settings, the command is not displayed. Do you know how to display it ?

.Then I 'd like to get the selected rows of the first ALV. The command to valid the select the rows is out of the first ALV. DO you have a method to do so or an example ?

Thanks for help,

Bertrand.

Hi,

In the layout set

DATA: w_layout TYPE lvc_s_layo.

w_layout-sel_mode = 'A'. U will get the buttons for selecting multiple rows.

This code will help u to get the selected rows.

Refer this code

INCLUDE <icon>.
 
* Predefine a local class for event handling to allow the
* declaration of a reference variable before the class is defined.
CLASS lcl_event_receiver DEFINITION DEFERRED.
CLASS cl_gui_container DEFINITION LOAD.

       o_dockingcontainer TYPE REF TO cl_gui_docking_container,
       o_eventreceiver    TYPE REF TO lcl_event_receiver.
CLASS lcl_event_receiver DEFINITION.

  PUBLIC SECTION.
    CLASS-METHODS:

            IMPORTING e_ucomm.
ENDCLASS.
CLASS lcl_event_receiver IMPLEMENTATION.
  METHOD handle_user_command.

    CASE e_ucomm.
 
      WHEN 'FCODE'.
 
        CALL METHOD o_alvgrid->get_selected_rows
          IMPORTING
            et_index_rows = i_selected_rows
*            ET_ROW_NO     =
            .
 
        IF i_selected_rows[] IS INITIAL.
          MESSAGE i153 WITH text-009.
          LEAVE LIST-PROCESSING.
        ENDIF.
 
        CLEAR: w_reviewed_mat.
 
*        w_reviewed_mat-reviewed = c_x.
*        w_reviewed_mat-reviewedby = sy-uname.
*        w_reviewed_mat-reviewedon = sy-datum.
 
        LOOP AT i_selected_rows INTO w_selected_rows.
          READ TABLE i_output INTO w_output INDEX w_selected_rows-index.
          IF sy-subrc EQ 0.
            w_reviewed_mat-matnr = w_output-matnr.
          ENDIF.
          APPEND w_reviewed_mat TO i_reviewed_mat.
          CLEAR: w_reviewed_mat-matnr.
        ENDLOOP.
 
*        MODIFY zzcs_mat FROM TABLE i_reviewed_mat.
 
      WHEN OTHERS.
 
    ENDCASE.
  ENDMETHOD.
 
In PBO after creating container 
SET HANDLER o_eventreceiver->handle_user_command  FOR o_Alvgrid.

This solved ur problem or not?

Hello Bertrand,

If you are using OOPS ALV,to select one or more rows,you have to pass a layout structure in the method SET_TABLE_FOR_FIRST_DISPLAY.For ex:

DATA:gs_layout TYPE lvc_s_layo.

gs_layout-sel_mode = 'A'.

CALL METHOD gv_alv->set_table_for_first_display

EXPORTING

is_layout = gs_layout

You can append A,B,C,D based on your requirements.

'A'

Column and row selection

• Multiple columns

• Multiple rows

The user selects the rows through pushbuttons at the left border of the grid control.

'B'

Simple selection, list box

• Multiple columns

• Multiple rows

'C'

Multiple selection, list box

• Multiple columns

• Multiple rows

'D'

Cell selection

• Multiple columns

• Multiple rows

• Any cells

The user selects the rows through pushbuttons at the left border of the grid control.

To get selected rows,you can use the method GET_SELECTED_ROWS.

CALL METHOD gv_alv->get_selected_rows

IMPORTING

ET_INDEX_ROWS =

et_row_no = lt_selected_rows.

READ TABLE lt_selected_rows INTO ls_selected_row INDEX 1 .

READ TABLE gt_it_schd_lines INTO

gs_wa_schd_lines INDEX ls_selected_row-row_id.

Beejal

Thanks for your help,

I have a remaining problem.

The command to valid selection is not inside the alv grid. So the method doesn't catch the selected data of my grid.

Do you know how to resolve this problem.

Thanks in advance,

Bertrand.

Hello Bertrand,

You can get the selected row-index using the method GET_SELECTED_ROWS.Then you can loop through the internal table used in the alv to fetch the data.

READ TABLE lt_selected_rows INTO ls_selected_row INDEX 1 .

READ TABLE gt_it_schd_lines INTO

gs_wa_schd_lines INDEX ls_selected_row-row_id.

Here,gt_it_schd_lines is my internal table and based on the selected row-index (ls_selected_row-row_id),I can read my internal table to a work area gs_wa_schd_lines.Now the work area gs_wa_schd_lines will have the selected data of your grid.

If you want to validate the data in the selected row,you can bring it to the work area as shown above (gs_wa_schd_lines) and then validate it.

Regards,

Beejal

Hello,

What I was trying to say is that GET_SELECTED_ROWS doesn't catch the selected rows besause my command is not in the ALV. It is one of the transaction screen command (in the middle of the screen).

Thanks for help,

Bertrand

if the command is not in ALV u cant capture the selected rows.

Re: ALV OBJECT : get selected datas

If the button(command) is not inside the container then it will not work because what ever operation u are doing (ie, selecting of multiple rows )is specific to the container itself.
