How to preselect all rows before displaying ALV report

[Former Member]

I would like to select all rows before sending ALV Grid Display. User then can unselect couple of rows for further processing. How do I do that ?. Im using Method grid1->SET_TABLE_FOR_FIRST_DISPLAY for ALV Report Display. Any help appreciated.

Hi,

you can use method set_selected_rows of class cl_gui_alv_grid. Just loop through the the table you are going to display and add corresponding index to the work area, then append it to it_index_rows table.

DATA: it_selected TYPE lvc_t_row,
            wa_selected TYPE lvc_s_row.

LOOP AT it_your_table  TRANSPORTING NO FIELDS.
      wa_index-index = sy-tabix.
      APPEND wa_selected TO it_selected.    
ENDLOOP.

CALL METHOD grid1->set_selected_rows
      IMPORTING
        it_index_rows = it_selected.

I didn't test it right now, but i suppose it should work fine.

Thanks a lot for the reply. When should I call this method ?. before calling grid1->SET_TABLE_FOR_FIRST_DISPLAY or after ?

Sreenivas, I really think it wouldn't take much time to just copy and paste this code before and after method set_table_for_first_display, activate it and check which one is giving the correct result

I tried both before and after still no luck. But Im sure set_selected_rows might do the trick. I think we need to export params rathan import. What do you think ?

Ok,

I've started the editor and check my code. I made few small mistakes (like with this exporting/importing), here's the sample - correctly working - code:

DATA: it_selected TYPE lvc_t_row,
      wa_selected TYPE lvc_s_row,
      wa_sflight TYPE sflight,
      ltp_layout TYPE lvc_s_layo.

     SELECT *
       FROM sflight
       INTO TABLE gi_sflight.

ltp_layout-stylefname = 'CELLTAB'.
ltp_layout-sel_mode = 'A'.

LOOP AT gi_sflight INTO wa_sflight.
      wa_selected-index = sy-tabix.
      APPEND wa_selected TO it_selected.
ENDLOOP.

*   * Load data into the grid and display them
     CALL METHOD go_grid->set_table_for_first_display
       EXPORTING i_structure_name = 'SFLIGHT'
                 is_layout            = ltp_layout
                 i_save = 'A'
       CHANGING  it_outtab        = gi_sflight.


CALL METHOD go_grid->set_selected_rows
      EXPORTING
        it_index_rows = it_selected.

This time it is 100% correct.
