If you’ve ever copied the same piece of DAX logic three times and told yourself “this is fine”… this session is for you. User-Defined Functions bring a long-awaited concept to DAX: reusability. Instead of repeating logic across measures (and hoping you remember to update all of them later), you can define it once and use it wherever you need it—like a civilized human being. In this session, we’ll explore what User-Defined Functions are, how they work, and why they can dramatically improve the maintainability of your models. We’ll dive into the difference between VAL and EXP inputs (and why that distinction matters more than it first appears), and walk through a series of real-world use cases where UDFs genuinely simplify your life—not just theoretically, but in practice. Expect fewer copy-paste crimes, cleaner models, and at least one moment where you rethink how you’ve been writing DAX all along.

Dive deep into the world of Power BI as we explore two game-changing features: Calculation Groups and Field Parameters. This session will equip you with the skills to create dynamic and efficient reports that empower users to analyze data more effectively. Discover how to: 1. Simplify complex DAX calculations with Calculation Groups. 2. Enhance user interactivity using Field Parameters. 3. Combine these features for maximum impact in real-world scenarios.
