ALV OOPS - Calling same program again with same selection screen

Former Member — Wed, 12 Jun 2013 09:06:22 GMT

Hello Experts,

I have an Grid ALV created in OOPS.

Now, i have created a button on the application toolbar of the ALV for refreshing the vales. (i.e. Some fields were changed after calling a change transaction and i need to refresh my internal table to get them displayed)

So, on handle_user_command event for the ALV,

i have the following coding,

CASE e_ucomm.
       WHEN 'REFRESH_GRID'.
       SUBMIT ztest USING SELECTION-SETS OF PROGRAM 'ztest'.
ENDCASE.

Now, my report is being called and executed but select-options are not being used, hence ALV is displayed blank.

I have also tried :

SUBMIT ztest WITH p_id = p_id VIA SELECTION-SCREEN.
(P_ID is the only parameter i have on my selection-screen)

Then report is being and selection screen is automatically filled but how can i make it to execute as well.

I tried

CALL FUNCTION 'SAPGUI_SET_FUNCTIONCODE'
         EXPORTING
             functioncode                 = 'ONLI'.

But it does not work.

Help Appreciated.

Regards,

Rajat Bothra

Thanks Fred. But after posting, i myself tried this

WHEN 'REFRESH_GRID'.

PERFORM get_data. " Get data from DB table again

CALL METHOD r_GRID->REFRESH_TABLE_DISPLAY.

and it worked.

i should have tried more before posting maybe.

This option didn't strike me till now.

Closing the post now.

On user command, you just have to call REFRESH_TABLE_DISPLAY method of CL_GUI_ALV_GRID class. Submit report is not a good way of refreshing display.

just use these codes to refresh the alv:

DATA: go_grid TYPE REF TO cl_gui_alv_grid.

CALL METHOD go_grid->refresh_table_display.

Structure a little your repor, should look like

* some forms executed after start-of-selection
 START-OF-SELECTION.
   PERFORM load_data.
   PERFORM build_final_table.
   PERFORM display_data.
 * In the "user_command" of the screen
   CASE ok_code.
     WHEN 'REFRESH_GRID'.
       PERFORM load_data.
       PERFORM build_final_table.
       lr_grid->refresh_table_display(
         EXPORTING
           is_stable      = is_stable
           i_soft_refresh = i_soft_refresh ).
     WHEN 'BACK'.
       SET SCREEN 0.
       LEAVE SCREEN.
 * etc.
   ENDCASE.
