Problems when using RANKX on PowerPivot

Question

I'm trying to use the RANKX funcion to Rank some sales, my table looks like this

I want to have a third column called ProductRank that will rank the The products depending on the ProductTotal, this is what I have

=RANKX(ALL('Query'[ProductID]),'Query'[ProductTotal])

However, this is nor working :(

any help with this?

Thanks

Answer 1

If [ProductTotal] is a column then the following should work

=RANKX(ALL('Query'[ProductID]),CALCULATE(SUM('Query'[ProductTotal])))
