How to calculate current month values in CALCULATE?

[darkmetrics]

I have monthly data for sales in format like

I want to calculate current month sales for each channel and previous month sales for each channel. I create a matrix with channel in rows and current month values in columns:

but strangely I can not reference the date column inside my measure:

CurrentMonthSales = CALCULATE(SUM('SalesTable'[Sales]),
FILTER('SalesTable', YEAR('SalesTable'[Date]) = YEAR(TODAY())),
FILTER ('SalesTable', MONTH('SalesTable'[Date] = MONTH(TODAY()))
))

Hey @darkmetrics ,

I do not understand what you mean by: "... I can not reference the date column inside my measure."

Nevertheless, I would write the measure like so:

CurrentMonthSales = 
var __TODAY = TODAY()
var currentYear = YEAR( __TODAY )
var currentMonth = MONTH( __TODAY )
return
SUMX(
FILTER( 'SalesTable'
, YEAR('SalesTable'[Date]) = currentYear && MONTH('SalesTable'[Date] = currentMonth
)
, 'SalesTable'[Sales]
)

Hopefully, this helps what you are looking for.

Regards,

Tom
