This works when I Filter a column Duplicate rows are retained. Natural Inner Join creates a table with only matching records: Intersect. The two tables must have the same number of columns. You don't need to input column names because DAX is picking that up with the relationship defined in the data model (which is why you need to have a defined relationship to use these functions). The key feature of this relationship type is it allows you to join 2 tables together even if there are repeating values in the join columns in both tables – i.e, it does not require a primary key in one of the columns in one of the tables. The UNION function allows us to bring two or more tables together or layer one on top of another for as many as we want.
