Do not inherit Top N as Top N by a Cross Filter, if then inherit the N filtered Customers (as a Set).

If you cross filter from a Visual that Contains a Cross Filter (e.g. Customers Bar Chart with the Top 10 Customers) that is already filteres by another Visual (e.g. Business Unit) then it can happen that a third Visual does not show any Data.

Reason is that the Top 10 Filter in inherited and the Customer Filter is inherited too. But in this 3rd Visual the Selected Customer is maybe not one of the Top 10.

In my Opinion a Top x Filter should never been inherited by a Cross Filter. If then the 10 Customers should been inherited.
