Back button for ALV grid display

Former Member — Thu, 04 Oct 2007 04:21:47 GMT

Hi,

I have developed a ALV report using Grid Display.

NO oops concept has been used. So, I dont have a screen of my own.

after the alv output appears, i double-click on one of the rows and get a pop-up in which i modify some value and press ok to get a changed value for one of the fields in the alv output. Now, when i press the "BACK" button, i go back to the previous alv output (i.e. with the unchanged value for tht particular field), and then, again i have to press "BACK" button to go back to the selection-screen. Thus, i need to press the back button twice to go back to the selection-screen from the modified alv grid output.

My requirement is to go back to the selection-screen on pressing the "BACK" button just once.

I have tried using the Set pf-status thing, and user_command thing, but on pressing the "BACK" button the flow doesnt stop at user_command code in debugging mode.But if i try the same logic for double-click thing using When '&IC1', the flow stops at the user_command code. I am using the correct function code for the 'BACK' button.

I have even tried copying the standard gui status from se80-->function group SALV,still no positive result.

Please help me.

Thanks & Regards,

Tejas Savla

Hi,

You can code for that in User command sub-routine.

check sy-ucomm and say LEAVE LIST PROCESSING,

it will go back to selection screen.

Hi,

After modifying the value please write below command.

rs_selfield-refresh = 'X'.

it refreshes the ALV screen. Now click on Back button and please check whether it is going back to selection screen or not?

Thanks,
