    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

MichaelHenry  Thank you for posting this!  Did you find this in Microsoft's official documentation?  If so, would you be willing to post a link to the page?

 

Thanks!

You can acually do this in the merge query editor. If you press control while selecting columns there is a small digit indicating the order displayed for each column allowing you to join on as many columns as you want.
