ALV Grid refresh not working properly

guillaume_delorme · ‎2009 Jul 22

Hi all,

i want to refresh my alv-grid but after update of my internal-table and setting the 3 fields of rs_selfield ( rs_selfield-refresh = 'X', rs_selfield-col_stable = 'X', rs_selfield-row_stable = 'X'), the method cl_gui_alv_grid-refresh_table_display only shows the data of my internal Table BEFORE my update... (i checked in Debugging the content of the table mt_outtab->*).

I wanted to add the fact, that i already checked ALL forum threads with keywords ALV GRID REFRESH and NONE of them solved my issue.. (all Reports of Michel Prioud for instance, the SLIS-ones)

*Here's an extract of my USERCOMMAND*_

CASE p_ucomm.
(...)
    WHEN '&AKTU'.
      PERFORM itab_actualize CHANGING gt_outtab. "<- actualization of my internal table
      rs_selfield-refresh = 'X'.
      rs_selfield-col_stable = 'X'.
      rs_selfield-row_stable = 'X'.
(...)
when others.
endcase.

Here's my ALV-Display-Call

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
      EXPORTING
        i_buffer_active             = 'X'
        i_callback_program          = g_callback_program
        i_callback_pf_status_set    = g_callback_pf_status_set
        i_callback_user_command     = g_callback_user_command
        i_callback_top_of_page      = g_callback_top_of_page
        i_callback_html_top_of_page = g_callback_html_top_of_page
        i_grid_title                = g_grid_title
        is_layout                   = gs_layout
        it_fieldcat                 = gt_fieldcat
        it_excluding                = gt_excluding
        it_sort                     = gt_sort
        it_filter                   = gt_filter
        i_save                      = g_save
        is_variant                  = gs_variant
        it_events                   = gt_events
        it_event_exit               = gt_event_exit
      TABLES
        t_outtab                    = gt_outtab
      EXCEPTIONS
        program_error               = 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.

Any idea on a possible explanation for this????

Thx in advance for any clue and greets from France...

CASE p_ucomm.

(...)

WHEN '&AKTU'.

PERFORM itab_actualize CHANGING gt_outtab. "<- actualization of my internal table

rs_selfield-refresh = 'X'.

rs_selfield-col_stable = 'X'.

Hi Guys,

Thx for your answers.

But:

->The first recommandation (clear itab and wa) was already implemented

->The second one is as you can see in my code already in too...

=>Sorry but the thread hasn't been answered yet ..

Greets,

Guillaume

Hi,

Try to debug and check weather gt_outtab is getting filled with new data or not....

CASE p_ucomm.

(...)

WHEN '&AKTU'.

BREAK-POINT.

PERFORM itab_actualize CHANGING gt_outtab. "<- actualization of my internal table

rs_selfield-refresh = 'X'.

rs_selfield-col_stable = 'X'.

rs_selfield-row_stable = 'X'.

(...)

when others.

endcase.

thnx

Rahul

guillaume_delorme · ‎2009 Jul 22

that's what i am doing since 8.00 AM (now 1.00 PM) => Itab get filled with updated Data => Dataretrieving-routine is OK...

Thx for your efforts Rahul,

Greets,

Hi GD,

Try this...

IF r_ucomm = '&ACTION'.

DATA ref1 TYPE REF TO cl_gui_alv_grid.

CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = ref1.

CALL METHOD ref1->check_changed_data.

...

....

*refresh the ALV Grid Display after the execution of the BDC

gt_display[ ] = gt_not_select[ ].

rs_selfield-refresh = c_x.

ENDIF.

thnx

Rahul

any update?

guillaume_delorme · ‎2009 Jul 22

Hi Rahul again...

absolutely no influence of the call-Method grid->check_changed_data on the report behaviour noticed...

=> Always refreshing but still showing the old datasets...

Thx again and Greets,

Guillaume

Hi Guillaume

Did you got the solution, I am also facing the same kind of problem.

I am using field-symbols for creating the structure . As my fieldcat depends on the number of characteristics maintained in a Z table.

I am getting the updated values, but doesn't reflect in ALV.

I have tried

1. rs_selfield-refresh = c_x.

2. CALL FUNCTION 'GET_GLOBALS_FROM_SLVC_FULLSCR'

IMPORTING

e_grid = ref_grid.

CALL METHOD ref_grid->refresh_table_display.

3. CALL METHOD ref_grid->check_changed_data .

But none of them works.

Please reply ASAP.

Regards,

Mukesh Dhakar

Hi Guillaume,

my bet: Although you modify the internal table data you re-fill them with original data again and then call display again. Make a where-used-list for the GT_DATA table, put breakpoints weherever it is filled and then try again. You will find out that your logic will re-fill the table.

Regards,

Clemens
