Calculate Rows of a Measure

Dalla_Terra , This because of row context and recalculation of measure grand total. The context of Grand total is also year and input is last year, that is why you see only last year

So one way out is that ytd/this year you use

sum(Depletion[Total 9L])

or try this

new YTDTY  = Sumx(Values(Dates[Year]),[YTDTY])

Thanks to you both, your feedback put me on the right path to come up with the modifications I needed to make to make my calc work. 

Previously my measures were: 

• YTDTY = TOTALYTD(sum(Depletion[Total 9L]),Dates[Date])

• YTDLY = TOTALYTD(Sum(Depletion[Total 9L]),SAMEPERIODLASTYEAR(Dates[Date]))

• YTD Var = [YTDTY]-[YTDLY]

I modified my YTDTY and YTDLY as follows: 

• YTDTY = Sumx(Values(Dates[Year]),TOTALYTD(Sum(Depletion[Total 9L]),Dates[Date]))

• YTDLY = Sumx(Values(Dates[Year]),TOTALYTD(Sum(Depletion[Total 9L]),SAMEPERIODLASTYEAR(Dates[Date])))

 

Leaving my YTD Var the same gave me what I was expecting to see
