Thanks DAVID BERRY. Your suggestion has helped to understand other related issues/request as well. I wondered when I am checking the case entity, there are only two associated record i.e Activities and connections. But there are many 1:N relations have been setup with Case entity.
When you said that to show the associate records we need to add the lookup field to the Form and view. That sounds really great and I was looking for this answer.
Cheers,
