refreshing ALV-list ?

Former Member — Tue, 08 Apr 2008 14:02:09 GMT

hi,

i am calling a alv-screen with FM REUSE_ALV_GRID_DISPLAY

as the output-table changes in some situations, is it possible to 'refresh' the alv-out-tab automaticly in ABAP ?

Try this way

Pl. check for rs_selfield-refresh = 'X' in the below mentioned code


    call function 'REUSE_ALV_GRID_DISPLAY'
      exporting
        it_fieldcat                 = i_fieldcat[]
        is_layout                   = pt_grplayout2
        i_callback_program          = 'YATTU0007'
        i_callback_html_top_of_page = p_header
        i_callback_user_command     = f_user_command1
        it_events                   = i_events[]
      tables
        t_outtab                    = i_yatthdr.
*
*&---------------------------------------------------------------------*
* Form  f_user_command1                                                *
*&---------------------------------------------------------------------*
* This form will handle the user command from fm REUSE                 *
*----------------------------------------------------------------------*
form f_user_command1 using p_ucomm type sy-ucomm
                     rs_selfield type  slis_selfield.

  data p_ref1 type ref to cl_gui_alv_grid.
  call function 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    importing
      e_grid = p_ref1.
  call method p_ref1->check_changed_data.
  case p_ucomm.
  endcase.

  rs_selfield-refresh = 'X'.            " Grid refresh

endform.                                 " F_user_command1

I think you need to call


  rs_selfield-refresh = 'X'.            " Grid refresh

after this call


data p_ref1 type ref to cl_gui_alv_grid.
  call function 'GET_GLOBALS_FROM_SLVC_FULLSCR'
    importing
      e_grid = p_ref1.
  call method p_ref1->check_changed_data.

i found another way:

i just do a modifiy on the grid-table !

but i think this is more the 'quick and dirty' way, isn't it ?

the problem is more complex:

i have to redirect the abap to the whole logic of creating the alv-out-tab ! it does NOT help me just to say 'refresh'

Hi Martin,

If you want to manually refresh ALV using REFRESH button on application toolbar, try this


FORM USER_COMMAND ..................

CASE P_UCOMM.

*refreshes  ALV Grid
    When '&NTE'.
      SUBMIT <PROGRAM_NAME>.            <---give the same program name

ENDCASE.

hi,

that does not sound very logical for me. i can't call the programm again, as there are complex parameters and select options in it ! i have to start it exactly with the SAME parameters !

reg, Martin

btw: i can't find an 'refresh button' in alv !?!??!?!

well, there is a new question:

is it possible to have an flexible ALV-header ? e.h. when i click on a specific line in alv data should be placed in the HEADER of alv !

Hello Martin

You may have a look at sample report ZUS_SDN_FM_ALV_REFRESH in

The report demonstrates how to refresh the ALV list. However, this has to be done manually.
