A&R solution is configured for Hierarchy.

All the contacts ( Hierarchy has 3 stages )I just scrolled 3 steps (Parent child, grand parent)

In the Account form we have added a rollup field Number of contacts which calculates all contacts in the account A and R solutions.

I added one contacts now it is 22

All these 22 contacts need to be displayed in contact entity view ( Any thing personal or System)

But the desired result is not matching with the number of contacts its mismatching.

However, I have referred a document and found that

I am bit Unsure about that, but based on my understanding condition cannot be connected by OR in the filter of a view, because they are all in the related entity. Only the fields in the same entity can be connected by OR.

We need to modify the fetch xml in order to get all contacts, we wish we need a OOB feature to add in the views
