    Aggregating fields and identifying unique values

    Navin Manglani

      Hi!  I've created a dummy data set so you can help me solve the problem with my real one (which has millions of rows and I can't post here).  In the table attached, I'm trying to identify "new" customers tied to a sale.   I want a field that will identify whether a transaction involves a new customer or not.  Can you help me create a calculated field that would do that?  I can do it in SQL, but can't do it in Tableau.  Thanks!
