Thank you Greg_Deckler for providing me 2 different options, the column is going to work better for my scenario and it worked perfectly!
I've been struggling to learn DAX - do you have any resources to suggest? I'm ok at very simple DAX functions but what you provided I would have never even thought of.
Thank you!
mvgust - There's an Introduction to DAX section here: https://docs.microsoft.com/en-us/power-bi/guided-learning/
Radacad has some great stuff. https://radacad.com/
If you are coming from SQL, Phil_Seamark 's DAX book is great. I think he has a new one Pro DAX too. I haven't read that one yet but if it's from Phil, it's gold.
MattAllington has some great DAX books
marcorusso 's Definitive Guide to DAX is, well, it's the gold standard. Maybe a bit theory heavy but unbeatable in terms of coverage of the DAX language.
I like my book, DAX Cookbook, as a more practical guide, not nearly so much theory as just straight-up practical DAX implementation strategies for metics, KPI's, etc. to solve real world problems.
Another great resource is the Quick Measures Gallery: https://community.powerbi.com/t5/Quick-Measures-Gallery/bd-p/QuickMeasuresGallery?sortby=kudos
A lot of my stuff ends up in there. Lots of crazy inventive DAX.
Very much depends what you are into, how you learn, etc.
