Hi Bri, I'm not quite with you - are you talking different Excel workbooks, or different Tableau workbooks ?
Do the dimensions and measures "sorta" line up ?
Any chance you can provide some dummy data that helps show what you're trying to achieve ?
I'm working with different Excel workbooks and combining them to see if the data is a equal (or which points are different). I am not able to provide dummy data because in other instances I have no trouble completing this.
