Overview and Outline

Once we get past the first CALCULATE statement in DAX our Excel thinking (in terms of Cells) shifts a bit. It shifts into thinking of Tables and Columns as variables. And as we try to grasp the concept of »the Filter Context« we see that it’s basically all about connections and table interactions.

Once you get to this stage that is when you start using CALCULATE (and other DAX functions) not just to add to Filter Context but to manipulate it. And this is where writing measures become an Art form. In this Masterclass we are going to learn to paint alongside the best of them.

It is necessary for the participants to have basic knowledge of Power BI and of the programming language DAX.

Software & Technical requirements

Please have at least the August 2022 version of Power BI Desktop installed. We will also be using DAX Studio for Power BI.
