DAX Functions in Power BI

Overview

Data Analysis Expressions (DAX) allow you to take your Power BI skills to the next level by writing custom functions.

DAX, or Data Analysis eXpressions, is a formula language used in Microsoft Power BI to create calculated columns, measures, and custom tables. Once mastered, DAX gives you powerful control over visuals and reports, allowing for better performance and more flexibility. This course covers the core concepts such as row query and filter context, with exercises focusing on filtering, counting, ranking, and iterating functions.

Syllabus

Setting up Data Models with DAX

In this chapter, you'll write custom functions to create new tables and calculated columns.

DAX and Measures

In this chapter, you'll write custom functions to create calculated measures. You'll also get introduced to variables to make writing DAX functions more efficient.

Filtering and Counting with DAX

Expand your DAX power with some commonly used DAX measures. This chapter focuses on filtering and counting functions.

Iterating Functions

This chapter covers the core concept of another powerful set of DAX functions, the so called iterating functions. You will explore iterations with exercises focusing on ranking and iterating your data.
