problem in Back button for a report

Former Member — Thu, 10 Dec 2009 06:08:39 GMT

Hi All,

I have a custom GUI status with an added refresh button in the application toolbar.

Now my problem is the back button.

I want it to go back to the programs selection-screen, not to the last program display.

What is happening now is let's say i click the refresh button 5 times, it took me another 5 click on the back button before it goes to the selection-screen.

How to do that?

Thanks.

There's no code for back button because it's a copy of the STANDARD_FULLSCREEN.

Only the refresh button is customized. When I tick the back button, the user command for the alv grid is not trigerred.

Take note that this is not dialog programming.

you need to code sy-ucomm &F03, if you are using the standard.

leave list processing will work in that case.

like in my case frm selection screen execution i am calling the ALV FM, and it automatically controls the same..

If its ALV LIST/GRID

CALL FUNCTION 'REUSE_ALV_LIST_DISPLAY'

EXPORTING

I_CALLBACK_PROGRAM ........................

I_CALLBACK_USER_COMMAND = 'USER_COMMAND'

IT_FIELDCAT = FCAT[]

IT_EVENTS = IT_EVENTS[]

TABLES

T_OUTTAB = LT_TAB.

FORM USER_COMMAND USING F_UCOMM LIKE SY-UCOMM

RS_SELFIELD TYPE SLIS_SELFIELD.

IF F_UCOMM = '&F03'.

LEAVE LIST PROCESSING.

ENDIF.

ENDFORM.

If its report program

AT USER-COMMAND.

IF SY-UCOMM = '&F03'.

LEAVE LIST PROCESSING.

ENDIF.

if you are using the standard ALV FM..then it is not required to give the code in the call back routine...

standard program automatically controls the behaviour of back button.

i place a break-point on the user-command, but it wasn't trigerred whenever i click 'back' it's only trigerred when i click refresh.

once again, refresh is a custom button while back is not.

did i miss something?

do i need to change something in SE41 for the back attribute?

it seems that i'm not in control of the back button.

if you have the Global trade active in your system ...you can refer to a program "RWB2_EXPENSE_WORKBENCH"

i think this is the same scenario...and its working for me..

You problem may not relate with BACK function code but with REFRESH, how did you manage it, don't call another ALV but refresh the display using rs_selfield-refresh = 'X' in the ALV user_command, then the back button should work perfectly. (You may also get memory problem, try to refresh 100 times, and check memory usage...)

i changed the fcode and the breakpoint is now triggered. but the LEAVE LIST PROCESSING is not working, my code now won't exit from the main alv display.

i think raymond suggestion might be right..

when you are refreshing it...just change the data in the internal tables that you were passing in the FM...

Re: problem in Back button for a report

Former Member — Thu, 10 Dec 2009 07:13:02 GMT

I am using the global tables to pass the data to the ALV...

once i press the refresh button..i update the data in the global tables...

that is all is required...it automatically updates the data in the ALV...

i think that will solve you issue..

Re: problem in Back button for a report

yup i call a new alv.

because in the refresh, i also need to capture the new created PO (in my case).

so in the refresh button, i call the subroutines that retrieves data and then call the alv back again.

Re: problem in Back button for a report

case fcode = 'REFRESH'

- ALV refresh

p_rs_selfield-refresh = yes.

p_rs_selfield-col_stable = yes.

p_rs_selfield-row_stable = yes.

PERFORM select_data_from_db_expense "... "REFRESH

TABLES gt_wbrk_list "...

gt_selected_doc_key.

..here gt_wbrk_list ..gets updated...and will update the ALV.

and GT_WBRK_LIST is the global internal table that i used firstly to pass the data to the ALV

In the user_command, you may have some code like

  WHEN 'REFRESH'.
    PERFORM load_full_data.
    rs_selfield-refresh = 'X'.
  WHEN 'CREATE'.
    PERFORM create_new_record CHANGING record retcode.
    IF retcode = 0.
      ADD record TO itab.
      rs_selfield-refresh = 'X'.
    ENDIF.
  WHEN 'DELETE'.
    PERFORM delete_old_record USING p_index CHANGING retcode.
    IF retcode = 0.
      DELETE itab INDEX p_index.
      rs_selfield-refresh= 'X'.
      rs_selfield-col_stable= 'X'.
      rs_selfield-row_stable= 'X'.
    ENDIF.
  WHEN OTHERS...
