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.
