There are many ways to do it, and I will show you now some examples of DAX functions that will allow you to join tables. The common approach to obtain a JOIN behavior in DAX is implicitly using the existing relationships. Column names from table parameters must all be different in all tables or an error is returned. You can do the same types of joins in DAX as you do in Power BI. A table that contains the Cartesian product of all rows from all tables in the arguments. name is a string representing the column name to use for the subsequent expression specified.

I got that to work via the “add a table based on a data model tab and then right click on the table and Table->Edit Dax” trick. DAX SUMMARIZECOLUMNS function is categorized under Filter functions.SUMMARIZECOLUMNS, is a replacement of SUMMARIZE and does not require the use of ADDCOLUMNS .. Purpose of DAX SUMMARIZECOLUMNS Function. Hi, ... only understood in summerizeColumns have better performance and SUmmerizecolumns will apply filter context later after cross join and we can't use same column twice in summerizecolumns.
