    Hey,

     

    in the query editor

    1. duplicate the columns that you want to use for the join
    2. mark the duplicated columns you want to use for the join, choose "Merge columns" from the context menu.

    Here is a screenshot:

     

    Repeat this for the 2nd table.

     

    Now you are able to use this column to create a relationship between both tables

     

    Don't forget to "hide" this column from report view.

     

    Hopefully this answers your question

     

    Regards

    Tom

Thanks for the tip! I have a question regarding "relationship", is it like "join" in SQL? If it is, what would be the equivalent in "relationship" to inner join/ outer join?

I usually write sql in ssms to create tables in powerbi. When multiple fields make up the PK, I do a CONCAT field in the sql query and use that in powerbi to join tables
