In that case, it might be time to upgrade your DAX skills to the next level. In this training day you will learn some of the more advanced DAX concepts. First, you get a brief refresh on the topics of row and filter context. Then you dive deeper into the following DAX concepts:
Expanded tables
Context Transition
Iterators
Calculation Groups
Windowing functions
Visual Calculations
