One of the most powerful, underrated features in Tableau Prep is the Difference From or "Multi-Row Formula" function. It allows you to calculate the difference in values between rows of data. This is useful when you need to calculate the time elapsed between dates or the general difference in values (e.g. dollars, counts, temperatures) from one row to the next. This kind of calculation is only available in Tableau Desktop with a Table Calculation which is limiting because Table Calculations can only execute against data that's present in a worksheet. Pre-calculating differences in the underlying data can be a game-changer! If you're looking to harness the power of SQL's LOOKUP/PARTITION in Tableau Prep, look no further!
