Hi all,

I am trying to implement the cumulative values measure in MS Power BI - (which is supposed to be the engine for Excel Power BI).

I have attempted to follow the tutorial on http://www.daxpatterns.com/cumulative-total/.
I've created and loaded a date table.

I've created a relationship between Datekey[date ] and PBI_KPIs[DateTo]

I've copied in the dax code

CumulativeGCI = 
		FILTER(ALL(DateKey[Date]), DateKey[Date] <= MAX (DateKey[Date])
and the .... thing won't work.
can anyone spot my error?
