In this chapter, we will focus on how to use DAX variables and the overall impact of using them in your code. The usage of DAX variables will not only improve the re-usability of your code but potentially make it more efficient as well. Apart from this, we will talk about the recommended formatting rules for DAX code and how using these features will help us identify and debug errors in our code.
Then, you will be introduced to the VAR and RETURN keywords and will learn how to effectively use them within your DAX code. We will also go through a practical example of using variables and formatting rules to debug a DAX measure that is not working correctly.
This chapter has been broken down into the following sections:
- Getting started with DAX variables
- Formatting your DAX code
- Debugging errors in your DAX code
