How to Create Variables in DAX — DAX in Power BI — Chapter 2
Learn how to use DAX variables in Power BI to make calculations easier to understand and for improved readability, consistency and performance.
When I was studying DAX, I realized how variables are helping to improve performance, readability and reduce the complexity of any DAX calculations.
During this learning process, I put my understandings in this blog. Let’s start our journey to DAX variables.
If you have missed my previous blog about Introduction to DAX, then please have a look to refresh your idea about DAX.
What is the DAX Variable
In DAX calculation, we can use variables to make the calculations easier to understand.
When you are writing any complex or nested expression using DAX functions, variables can help to break these complex calculations into smaller, more useful sections.
Why we need DAX variable
You can use variables in any form of DAX calculations and it includes calculated measures, columns and tables.
A type of variable is nothing but the calculated object type in DAX
