Portal Call

Hi Experts,

Im a HR person. I have the doubt regarding the Portal RFC call. Consider I have one portal screen and it has the button like "click here for details". Now when user click the button some screen will displayed. Now I want to know how the screen was called and from where the screen is designed?

Whats going on in background? How can I identify the process?

Thanks in advance,

All helps will be highly appreciated.
