Calculate a metric with OR logic from two different tables

[dkernen]

Hello.  I believe I have a relatively simple ask but one that I cannot figure out.

I have included a link to a sample dataset.  https://mwtn-my.sharepoint.com/:u:/g/personal/dkernen_mwtn_org/EZt6qdxeDXhJpZjw3Jaay4wBe5-VaTaxIwgjy...

I have three tables: dimension for SHAPES, dimension for COLORS, and a fact for SALES.  I know how to make measures for when color="Red" or when shape = "Round"  or when color=Red AND shape="Round" but I need to create a measure for when color="Red" OR shape="Round"

Any help would be most appreciated!  Thank you so much!

Hi @dkernen - have you tried adding the separate results of "where color = red" and "where shape = round" ?  This would double-count those that are red and round, so you could then subtract "where color = red AND where shape = round".

RedOrRound = 
var __Red = CALCULATE([Total Sales], Colors[Color] = "Red")
var __Round = CALCULATE([Total Sales], Shapes[Shape] = "Round")
var __RandR = CALCULATE([Total Sales], Colors[Color] = "Red", Shapes[Shape] = "Round")
return
     (__Red + __Round) - __RandR

Hope this helps
