How to handle/get event id on SC.

Hello Experts,

I have added a custom button on SC in component FPM_OIF_COMPONENT configuration /SAPSRM/WDCC_FPM_OIF_SC_PROFNL. Also I have defined my ZACTION and assigned to the BUS2121.

Now I want add my logic when I press on button. I have created a enhancement on View CNR_VIEW method ONACTIONBUTTON_PRESSED, but I don't know how retrieve the event id once I press the button.

Any idea to do it?

Many thanks.
