Calculate the current date minus 6 months in a DAX measure

[webportal]

I want to calculate the current date minus 6 months in a DAX measure:

MyMeasure = 
DATEADD('Calendar'[Date], -6, MONTH)

Returns a table.

In a matrix where 'Calendar'[Date] is on the rows, this measure returns an error, because the result of the measure is a table and not a scalar.

How to convert this into a scalar?

Thank you

@webportal Try:

MyMeasure = 
  VAR __Date = MAX('Calendar'[Date])
  VAR __SixMonthsAgo = EOMONTH(__Date,-6)
RETURN
  DATE(YEAR(__SixMonthsAgo),MONTH(__SixMonthsAgo),DAY(__Date))

@webportal can you adjust your measure to:

Measure = CALCULATE ( MAX ( Calendar[Date] ) , DATEADD ( 'Calendar'[Date] , -6 , MONTH ) )

The EDATE function gives you the date N number of months forward or backward of a reference date. For example, if we start from our sales table and calculate the date of the last sale and we want to calculate the date 6 months before that date the code would be as follows:

closes 6 months ago = EDATE(LASTDATE(Sales[Date]),-6)
