The UI Gets You 75%, M Gets You Over the Line.

You use the Power Query interface because it’s great - I do too. And you already know how to build queries. This session is about making them last over time: fewer fragile steps, fewer “why did this break?” moments, and a set of practical patterns you can apply across models, dataflows, and files without making it complicated.

Visual calculations

Power BI visual calculations have been around for a while, and even though the feature hasn’t reached general availability, its use cases are expanding rapidly. Visual calculations let you define calculations directly at the visual level, reducing the need for complex DAX and enabling faster insight creation. In this session, we’ll dive into what they are, how to use them, which exclusive visual calculation functions exist, and how you can combine them with DAX UDFs to create reusable visuals easily!
