How did you get 2 extract. Data source / Flat files ( CSV, excel) etc.
Before creating 2 extracts , why do not you join original sources in tableau then create an extract.
Hope it helps.
Thanks for looking into this.
My extract 1 is created from another extract that sits on tableau server
Extract 2 is created from a live datasource that also sits on tableau server
I can not join server datasources, which is why I had to do that. Open to suggestions here.
