Advance BI Analytics - Calculating % of Total Database
I love the idea of the new Advance BI Analytics platform but am struggling with something pretty basic and hope someone can help me out. I'm trying to build a Database Health dashboard to call out the items that need to be removed from Marketo. This includes outright junk, people missing emails, Leads that were never converted, etc. I can't figure out how to show a % of the total database for each of these items. We can't create new measures so the approaches in the Power BI community are not viable. How the heck do you create a card showing the % of total leads in my database that don't have email addresses?
Has anyone undertaken this type of database health reporting exercise in the new reporting platform that could give me some tips?
