    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

I got this to work by selecting the first join columns, then holding control to select the second join columns under "Merge Queries."

I just tried this, and it's amazing. Never would of guessed you can do multiple joins by holding control. Wish this was also available for relationships.
