Intermediate to advanced • Filter context & CALCULATE • Time intelligence • DAX performance & optimization
Course Description
This focused, advanced DAX course is for analysts and report builders who already know the Power BI basics. You will master the calculation engine behind Power BI — filter context, CALCULATE, time intelligence and performance — so your measures are correct, fast and reusable.
DAX is hard to learn alone because filter context is invisible until someone shows it clearly. The course is built around making that concept intuitive, with hands-on exercises and, where possible, your own measures and data so the learning transfers straight to your reports.
What You Will Learn
- ✓DAX Foundations — Syntax, data types, operators and the difference between calculated columns and measures — done properly from the start.
- ✓Filter & Row Context — The single most important concept in DAX: how context flows, and why the same measure gives different results in different places.
- ✓CALCULATE — Master context transition and CALCULATE — the function that unlocks the vast majority of real-world business calculations.
- ✓Time Intelligence — Year-to-date, month-over-month, year-over-year and rolling averages built on a proper date table.
- ✓Iterators & Variables — SUMX, AVERAGEX and friends, plus VAR to write DAX that is readable, testable and easy to maintain.
- ✓DAX Performance — Understand the storage and formula engines, spot slow patterns, and optimise measures for fast reports.

Power BI DAX — FAQ
What level is this course?
Intermediate to advanced. It assumes you can already build a basic Power BI report. If you are brand new, start with Power BI Essentials.
Why is DAX so hard to learn on your own?
Because filter context is invisible until someone shows it clearly. This course is built around making context — the concept most people get stuck on — intuitive.
Do we use real examples?
Yes. We work through finance and operations scenarios, and where possible your own measures and data, so the learning transfers directly to your reports.
Online or in person?
Both — live online across the UAE, or on-site in Dubai for teams.
Will this help with the PL-300 exam?
The DAX topics here overlap strongly with the modelling and calculation areas of Microsoft’s PL-300. We also offer dedicated PL-300 Exam Preparation.
Can it be customised for my team?
Yes. We tailor the depth, pace and examples to your team’s current skill level and reporting needs.
