Welcome to Introduction to DAX for Power BI. This two-day instructor-led course is intended for business users who have been using Power BI and want to use DAX to create custom calculations in their data models. In this class, you will be introduced to using Data Analysis Expressions (DAX), which is the expression language that is used to create custom calculations in the Power BI Data model. The course covers some of the theoretical underpinnings of the data model and the DAX language, but the emphasis is on using DAX to solve common business problems. You will learn how to write your own calculated columns, measures, and tables, how to visualize the way Power BI computes DAX calculations, and how to troubleshoot custom code.

Learning Objectives

At course completion, you should be able to
describe DAX syntax, data types, and errors
use DAX to create calculated columns, measures, and tables
explain how DAX calculations are evaluated, along with the differences between row context and filter context
configure and use Time Intelligence to perform common time-based calculations, for example to-date calculations, year-over-year analysis, moving averages, etc.
create calculated columns and measures that use data from multiple tables in the data model
write measures that handle error conditions gracefully
use DAX to enhance the Power BI user experience
