Create Fiori app using Three level CDS views with BOPF

Hello,

I am facing problem with creating three level CDS views with BOPF.

Actually I am trying to do below hierarchy.

-A (Root)

-----B(Child of A)

-----------C (Child of B)

I am facing problem of interrelating these ABC views using association type annotation as per expected above hierarchy.

Kindly share examples which can help for the same.
