Same Period Last Year with Filter
I simply want to return results from last year based on the number of months that have passed this year. So this year would be January through October have passed. I want to get last years results January through October, so I'm trying to filter using MAX Calendar Date. This below is not working and is computing the results of this year and not last year.
GA LY = CALCULATE([Gross Adds],FILTER('Calendar','Calendar'[CalendarDate]=MAX([Calendar Date],SAMEPERIODLASTYEAR('Calendar'[Calendar Date]))))
GA LY = var m = max('Calendar'[CalendarDate]) return CALCULATE([Gross Adds],SAMEPERIODLASTYEAR('Calendar'[Calendar Date]),'Calendar'[Calendar Date]<=EDATE(m,-12))lbendlin Found this on Marc Russo's blog, if anyone needs a solution. This works:
PY Last Day Selection = VAR LastDaySelection = LASTNONBLANK ( 'Calendar'[Calendar Date], [Gross Adds] ) VAR CurrentRange = DATESBETWEEN ( 'Calendar'[Calendar Date], MIN ( 'Calendar'[Calendar Date] ), LastDaySelection ) VAR PreviousRange = SAMEPERIODLASTYEAR ( CurrentRange ) RETURN IF ( LastDaySelection > MIN ( 'Calendar'[Calendar Date]),CALCULATE ( [Gross Adds], PreviousRange ))

GA LY = var m = max('Calendar'[CalendarDate]) return CALCULATE([Gross Adds],SAMEPERIODLASTYEAR('Calendar'[Calendar Date]),MONTH(MAX('Calendar'[Calendar Date]))<=MONTH(m))lbendlin Hi-I'm getting "The true/false expression does not specify a column. Each true/false expression used as a table filter expression must refer to exactly one column".

Hi lbendlin I thought it was working, but it only works if I filter the months in a slicer. Otherwise it still counts the whole year. I've run into this problem on several ideas I've tried. Do you know how I can get it to just calculate based on Max date of this current year?
