Another advantage of Power BI is how easily time intelligence can be added to your data model. Within data analysis expressions (DAX), you have a comprehensive list of built-in time intelligence functions to make this very easy. In this section, you are going to use these built-in functions to create the following measures:
- Year to Date Sales
- Year to Date Sales (Fiscal Calendar)
- Prior Year Sales
Built-in time intelligence calculations do not work if you are using a direct query connection to your data source rather than importing data. Take a look at the alternative methods for calculating time intelligence in the DAX cheatsheet at https://tinyurl.com/pbiqs-daxcheatsheet.
