How to perform a bottom of the application toolbar by codding?

Hi.

I tried to found info about this, it seems to be easy, but i couldn't found it.

I have a ALV Report (with funtion module not OO).

I copied a gui status from program saplkkbl status gui: standard_fullscreen.

In the ALV i have one column editable, i could refresh the info when i push the bottom that refers the function code &REFRESH

I add a buttom in the application toolbar, i would like to execute or perform the standard funtion '&Refresh', and after that do my own code.

how could i do it?

thanks!!!

Albio.-
