Cracking DAX – the EARLIER and RANKX Functions

So far in this series, Andy Brown of Wise Owl Training has shed light on functions like CALCULATE, VALUES and FILTER, but it’s only when you understand the idiosyncrasies of the EARLIER function that you can claim to have genuinely cracked DAX. This article gives four examples of the use of this peculiar function, in the process explaining why it has such a misleading name. Using the EARLIER function properly all boils down (as is so often the case with DAX) to understanding row and filter context. The article also shows how to use the RANKX function to sort data into your required order.

Question of the Day

Getting the Average

I have this data in the dbo.Commission table in a SQL Server 2022 database.

salesperson commission
Brian       12
Brian       16
Andy        7
Andy        14
Andy        21
Steve       20
Steve       NULL
All the data is a varchar, and I decide to run this query to get the totals for each salesperson.
SELECT SalesPerson
     , AVG(TRY_PARSE(Commission AS int)) AS TotalCommission
 FROM commission
 GROUP BY SalesPerson
GO
What average commission is calculated for Steve?
