alv and refresh

Former Member — Mon, 25 Feb 2008 17:55:31 GMT

Hy yall,

in my alv i make a call transaction, when u r in the transaction the back button works correctly and you are send back in the screen (alv) from where you were coming from.

WHEN '&IC1'.
      IF ps_selfield-fieldname = 'LF_QMNUM'.
*     Read data table
        READ TABLE tb_alv INTO wa_output INDEX ps_selfield-tabindex.

        SET PARAMETER ID 'IQM' FIELD wa_output-lf_qmnum.
        CALL TRANSACTION 'IW53' AND SKIP FIRST SCREEN.
      ENDIF.

the trouble start when i add a refresh button.

the call transaction is working well but when u back u r not in the screen you left (you have all the result instead of have the result you had after your select option.

that the code for the refresh

*    WHEN '&REFRESH'.
*      DATA i_rsparams LIKE rsparams OCCURS 0.
*
**      CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'
**      EXPORTING
**      curr_report = 'ZPM_VISUALIZZA_AVVISI'
** IMPORTING
* SP =
*      TABLES
*      selection_table = i_rsparams
*      EXCEPTIONS
*      not_found = 1
*      no_report = 2
*      OTHERS = 3
*
*.
*      IF sy-subrc = 0.
** MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
** WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
*      ENDIF.

  endcase.
*  SUBMIT zpm_visualizza_avvisi WITH SELECTION-TABLE i_rsparams.
*  ps_selfield-refresh = 'X'.

how can i modify my code in other to allow to back to the the screen i was be4 the call transaction?

thanx

Try this progrm u'll get an idea on refresh,

i'm on the way but it's not excactely what i'm trying to do. i don't need an automatic refresh. Only decide by the user.

My problem is that without the refresh button, i can call the transaction and back to screen, but with the refresh button active no. when i try to come back to the screen, the is refresh. i don't need the screen to be refresh when i come back from the transaction 'iw53'. I don't know i'm a little bit clearer

Hi,

Can you re-submit the exact full code that generate your problem (without comment signs)? Thanks

that the original code i use

CASE pw_ucomm.
    WHEN '&IC1'.
      IF ps_selfield-fieldname = 'LF_QMNUM'.
*     Read data table
        READ TABLE tb_alv INTO wa_output INDEX ps_selfield-tabindex.

        SET PARAMETER ID 'IQM' FIELD wa_output-lf_qmnum.
        CALL TRANSACTION 'IW53' AND SKIP FIRST SCREEN.
      ENDIF.

    WHEN '&REFRESH'.
      DATA i_rsparams LIKE rsparams OCCURS 0.

      CALL FUNCTION 'RS_REFRESH_FROM_SELECTOPTIONS'
      EXPORTING
      curr_report = 'ZPM_VISUALIZZA_AVVISI'
 IMPORTING
 SP =
      TABLES
      selection_table = i_rsparams
      EXCEPTIONS
      not_found = 1
      no_report = 2
      OTHERS = 3

.
      IF sy-subrc = 0.
* MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
* WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.

  ENDCASE.
  SUBMIT zpm_visualizza_avvisi WITH SELECTION-TABLE i_rsparams.
  ps_selfield-refresh = 'X'.
ENDFORM.

in that way, when i come back from the transaction instead of set the screen i was before the transaction, that screen has been refresh. Without the code part of the refresh button i can call the transaction and back without trouble. Am i clear enough?

If you are using alv in OO context, then you can do the follwoing for refresh:

WHEN '&REFRESH'.

CALL METHOD gv_alv_grid->refresh_table_display.

(where gv_alv_grid TYPE REF TO cl_gui_alv_grid).

no i'm unsing a classic reuse_alv_grid.

CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
      i_callback_program       = 'ZPM_VISUALIZZA_AVVISI'
      i_structure_name         = 'st_alv'
      i_grid_title             = 'Situazione avvisi'
      is_layout                = layout
      i_callback_user_command  = 'USER_COMMAND'
      i_callback_pf_status_set = 'STANDARD_FULLSCREEN'
      it_fieldcat              = l_t_fieldcat
      is_variant               = lt_variant
      it_events                = er_events[]
      is_print                 = print
      i_save                   = 'A'
    TABLES
      t_outtab                 = tb_alv.

is it better using ALV in OO context? what can be the advantage ( as u understand i'm a newby...)

Hi,

After reading your code, I am sure the statements after WHEN '&REFRESH' will not be executed after the calling of IW53. But the following SUBMIT will be executed. Do you really need to do it? If you do not need it delete this lines, and I am sure you will be back to your last list after calling IW53.

SUBMIT zpm_visualizza_avvisi WITH SELECTION-TABLE i_rsparams.

ps_selfield-refresh = 'X'.

After re-reading your code, I think you should put the ENDCASE statement after this SUBMIT statement.

ENDCASE. "Delete*

SUBMIT zpm_visualizza_avvisi WITH SELECTION-TABLE i_rsparams.

ps_selfield-refresh = 'X'.

ENDCASE. "Insert here!

That should solve your problem.
