Problem with my formula

Hi RonaldvdH 

I build a sample to show you how to get running total from another table.

Sales:

Date:

Date =
ADDCOLUMNS (
    CALENDARAUTO (),
    "Year", YEAR ( [Date] ),
    "Month", MONTH ( [Date] ),
    "MonthName", FORMAT ( [Date], "MMMM" )
)

Relationship: Date[Date] —— Sales[SalesDate] 

Measure:

Measure = 
CALCULATE(
COUNTROWS(Sales),
FILTER(ALL('Date'),'Date'[Date]<=MAX('Date'[Date])),
FILTER(ALL(Sales),Sales[SalesDate] <>BLANK())
)+0

Blank in SalesDate column will cause blank in columns in Date table in visual, due to relationship. Remove blank in Date column in Filter Field. Result is as below.
