I have two tables: FactAppointment and FactSales. These tables have true/false columns FactAppointment[NewPatient] and FactSales[FirstSale]. Both tables also contain the column "UserID".
I want a calculated column in FactSales which states:
IF FactAppointment[NewPatient] = TRUE AND FactSales[FirstSale] = TRUE AND UserID is the same, then TRUE, else FALSE.
How can I write this?
