Hi there. 

This is my first post, so let me just introduce myself quickly. I am currently taking the Project Leader course on behalf of a Danish partner. Im 3 weeks into the course, so I apologize if this is a stupid question.

The challenge:

I need to be able to analyse a companies turnover in some more granularity. 
Specifically, I want to be able to look at re-sales vs new sales (Returning vs. new costumers).

I am unable to find the right filter setting for this task. Can someone point me in the right direction?

Thanks in advance,

Lennart
