ALV Object model dump when calling method cl_salv_table-set_data by button

Former Member — Fri, 22 Feb 2008 13:10:19 GMT

Dear all,

i have 2 container with 2 OO ALV. In one of this Grids i like to change the assigned internal table data.

If i do this with pushbuttons from the Dynrpo Gui status, it is running.

But if i add Pushbuttons via method (->add_function) in one of the ALV grids and try to change table assignment in the event method, i get a dump raising CX_SALV_NO_NEW_DATA_ALLOWED.

In debugging i saw, that in case of calling the method via ALV pushbutton the attribute <function_call_active> is true, therefore no change in ALV is allowed:

if r_adapter->function_call_active eq abap_true.

value = abap_false.

endif.

My method to change ALV assigning:

class lcl_handle_events_post implementation.

method on_user_command.

data:

lv_header type lvc_title.

field-symbols:

<lv_tab> type any.

case e_salv_function.

when 'IFRS'.

v_list_type = const_ifrs.

assign t_ledger_ifrs to <lv_tab>.

lv_header = text-ifr.

when 'LOCAL'.

v_list_type = const_local.

assign t_ledger_local to <lv_tab>.

lv_header = text-lcl.

when 'TOTAL'.

v_list_type = const_total.

assign t_ledger_total to <lv_tab>.

lv_header = text-tot.

when 'POST'.

v_list_type = const_post.

assign t_posting to <lv_tab>.

lv_header = text-pst.

endcase.

ref_salvset_post->set_list_header( lv_header ).

try.

ref_salvtab_post->set_data(

changing t_table = <lv_tab> ).

catch cx_salv_no_new_data_allowed.

endtry.

ref_salvtab_post->refresh( refresh_mode = if_salv_c_refresh=>soft ).

endmethod. "on_user_command

endclass. "lcl_handle_events IMPLEMENTATION

Has anybody idea?

thanks a lot,

Wolfgang

Hello Wolfgang,

did you solve this problem? Doku of CL_SALV_TABLE->SET_DATA says that it is not allowed in eventhandler.

I am facing the same problem and tried to display new data in second grid with method REFRESH( full ) but it does not work. The grid does not change...

If you have a solution, please post it.

regards,

Herbert

Hello Herbert,

sorry, i havent seen your posting.

I only set a new okcode in this event so that i come into PAI and check the new okcode:

class lcl_handle_events_post implementation.
  method on_user_command.
    data:
      rc         type sysubrc.

    b_list_button = true.
    call method cl_gui_cfw=>set_new_ok_code
      exporting
        new_code = e_salv_function
      importing
        rc       = rc.

  endmethod. "on_user_command
endclass. "lcl_handle_events IMPLEMENTATION


module init_alv output.

* PBO is sent by function when pressing button in OO ALV
* to set new table assignment to OO ALV.
  if b_list_button = true.
    perform:
      alv_fill_top,
      alv_oo_fill_bottom.
...

form alv_oo_fill_bottom.
  if ref_salvtab_post is initial.
...
  else.

    try.
        ref_salvtab_post->set_data(
          changing t_table = <lv_tab> ).
      catch cx_salv_no_new_data_allowed.
    endtry.

    ref_salvset_post->set_list_header( lv_header ).
    ref_salvcols_post = ref_salvtab_post->get_columns( ).
    ref_salvcols_post->set_optimize( true ).

    case v_list_type.
      when const_total.
        perform alv_oo_rename_cols.

      when const_lines.
        perform alv_oo_rename_col_name using:
           'TYPE' text-a15 text-a16.
    endcase.

    free ref_salfun_post.
    ref_salfun_post   = ref_salvtab_post->get_functions( ).
    ref_salfun_post->set_all( ).

* enable / disable functions
    perform alv_oo_functions_status_set
      using ref_salfun_post.

    if b_color_table = true.
      try.
          ref_salvcols_post->set_color_column( 'COLOR' ).
        catch cx_salv_data_error.
      endtry.
    endif.
    ref_salvtab_post->refresh( refresh_mode = if_salv_c_refresh=>soft ).
