Hi ABAPers,

I am replcing the standard action of BACK button of an ALV report with number of editable field.I want , whenever users press BACK button , it will ask wheteher want to save the changes of the record of the editable field of the ALV report or not.

I am using the following code for this purpose.


gs_event_exit-ucomm = '&F03'.
gs_event_exit-before = 'X'.
append gs_event_exit to gt_event_exit.

  data answer(3).


  CASE r_ucomm.

    WHEN '&F03'.                " BACK BUTTON
 CALL FUNCTION 'POPUP_TO_CONFIRM_DATA_LOSS'
         EXPORTING
*          DEFAULTOPTION       = 'J'
           titel               = ' '
*          START_COLUMN        = 25
*          START_ROW           = 6
        IMPORTING
          ANSWER              = answer.


        if answer ne 'J'.
            leave program.
         else.
         r_ucomm = '&DATA_SAVE'.
         endif.

But the problem is that -

the popup is coming twice .

Can anybody help me to make it single time.

It's because you are keep on appending the data in gt_event_exit.

You need to append this entry only once. Bexcause with user interaction this event is getting appended multiple times and that's why the pop-up is coming again and again.

Please check it in debug mode.

Hi Richa,

i have debug the code. but the problem is not that u are saying.

the problem is when r_ucomm is not going to chage from &F03 to &DATASAVE in first run.
