Filter Context vs Row Context in DAX – Understanding Evaluation Context in Power BI

About the Course:

DAX (Data Analysis Expressions) enables calculations in Power BI, yet many users find its evaluation context challenging to master.

Distinguishing between Row Context and Filter Context is essential for creating accurate and reliable DAX formulas.

This session will clarify these concepts through practical demonstrations in Power BI. You will learn how context impacts calculated columns, measures, and report visuals.

By the end of the session, DAX will appear logical and structured rather than confusing.

Course Objectives:

• Clearly define both row context and filter context to ensure a solid understanding of their roles.
• Identify the scenarios in which row context is established.
