Extension points are one of the important constructs that designers of PRPC have baked into the product. As the name says it lets you to extend core functionalities of PRPC in a control manner as envisioned by the original designer of a particular module.
As a beginner when you first found out about extension points you were very exited and used this new found pattern to crack a problem with ease. After that for most of us the natural question was where else has Pega used this pattern while building the product. You do a PDN search and find a list of activities, but the real question is, is that it, have they documented everything in PDN, I do not think so.
So this attempt is to capture documented and undocumented Extension Points into one centralized place with the help of PRPC community.
