if you are looking for a truly deep dive into Time Intelligence Functions - check out the latest “Talk Power BI” on Avi Singh’s YouTube channel.
Jeffrey Wang (the Father of the DAX language) discusses how and why to use various Time Intelligence functions. As well as some understanding of why your functions may not be working exactly as expected.
While this was advertised as “for Beginners”, and there are some beginner tips (like turn off auto date), there is also some serious deep-dive going on.
I think almost everyone listening to the presentation learned something new.
I know this is one I’ll be re-watching with my complete focus on the presentation later (my first time through I was working on another screen at the same time).
