Course Overview

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.

Course Objectives

  • 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
  • Use DAX Studio to connect to a Power BI data model and execute simple queries
