EARLIER vs EARLIEST in DAX
The EARLIER() and EARLIEST() functions are 2 of the harder functions in DAX to get your head around. If you come from a programming background it will probably be easy for you. However as I have repeatedly stated on my blog, one of the many great things about Power BI is that it is accessible to mere mortal Excel users like you and me. You don’t have to be a classically trained IT programmer to be a Power BI report author. Inevitably however there will be harder concepts that you will indeed need to learn if you want to progress from a beginner to intermediate to an advanced user.
