    Limitation? Can't reference a calculated field in a join

    Sean Morris

      Hi all. If I understand correctly, there is no way in Tableau to use a calculated field as part of a join. So, if I use a substring expression to create a new column with term name (say, Fall2015) from a column that is in my original data source (where the original value is, say, "Fall2015FullTimeFirstTime"), that new column then doesn't appear in my list of fields on which I can join.


      To get around this, I would need to create the new column in Excel first, so that Tableau recognizes the column as part of the original dataset.
