DAX for Power BI videos | DAX for Power BI Part 3.1 - Relationships and the Related Function

Posted by Andrew Gould on 26 September 2021

This video explains some of the basic concepts of data models involving multiple tables in Power BI. You'll learn about one-to-many or many-to-one relationships and how to get Power BI to automatically detect relationships between tables. You'll see how to create relationships manually and learn some basic data model terminology. You'll see what happens when you have multiple tables which aren't related and how filters propagate through the relationships in your model. You'll also see how to manipulate the direction of a relationship to influence how filters behave. In the final part of the video you'll learn how and why to use the Related DAX function to reference fields in different tables.
