Learn valuable insights and strategies from industry experts.
DAX (Data Analysis Expressions) is the calculation language behind Microsoft Power BI, Analysis Services, and Power Pivot. While the basics of DAX can appear straightforward, many users quickly discover that creating accurate and efficient calculations requires a deeper understanding of how DAX really works. This webinar is designed to help participants build a strong conceptual foundation and avoid the most common beginner mistakes.
In this 60-minute session, Markus Ehrenmueller-Jensen will walk through five essential lessons that every DAX beginner should understand early in their learning journey. Using practical examples and real-world scenarios, attendees will learn the difference between calculated columns and measures, understand the importance of row context and filter context, and discover how context influences every DAX calculation.
The session focuses on helping attendees move beyond trial-and-error coding and toward a more structured understanding of DAX logic. Participants will gain practical techniques for writing more reliable and dynamic calculations while developing the confidence to troubleshoot common DAX issues.
Whether you are new to Power BI or already building reports and models, this webinar will provide valuable insights and several “aha!” moments that make DAX easier to understand and apply effectively.
• Introduction to DAX and its role in Power BI
• Why DAX feels simple but becomes complex
• Understanding evaluation context in DAX
• Calculated Columns vs. Measures
• Row Context explained with examples
• Filter Context explained with examples
• Context transition and why it matters
• Common DAX mistakes and how to avoid them
• Building dynamic calculations using measures
• Practical demonstrations and real-world use cases
• Tips for debugging and improving DAX calculations
• Recommended learning path for improving DAX skills
DAX is one of the most powerful — and often misunderstood — components of Power BI. Many users struggle not because the syntax is difficult, but because the underlying concepts of evaluation context are not fully understood. This webinar helps attendees build the right mental model for DAX from the beginning, enabling them to write better calculations, troubleshoot problems faster, and create more dynamic and interactive reports.
Participants will leave the session with practical knowledge they can immediately apply in their daily reporting and analytics work.
