When I put a breakpoint in the ABAP code and run the program, the first things I see on the call stack are these:
Transaction
PBO Screen
PBO Module
Can anyone explain what exactly they are?

Hi Ikim SS,
Your application is a module pool based application and that is the reason why you are able to see PBO & PAI, sometimes POH & POV too.
PBO -> Process before output ->PBO is triggered before the screen is displayed .
PAI -> Process After Input -> PAI is triggered after a user action on the screen
You can find many blogs in SCN about Module pool programming and even in SAP help.

Did you look in online help or your Abap course materials for the 'Process Before Output' dynpro event?
