What are the benefits of using variables in DAX?

Here are some benefits of using variables in DAX:

  • By declaring and evaluating the variable, a variable can be reused multiple times in the DAX expression so that we can avoid additional queries of the source database.
  • Variables can make DAX expressions more logical to interpret.
  • Variables are only used to their measure or query; they cannot be shared among measures, queries, or cannot be defined at the model level.
