LastYear Sales same period not calculated properly

[iLikeAzureSQL]

I need to have the sales for last year same period ( like 01/01/2015 to 06/10/2015) copmpared to this years to date sale

I'm using this DAX:

LY YTD Sales = CALCULATE([LY Sales],SAMEPERIODLASTYEAR(DateDimension[Date]))

LY Sales = CALCULATE([Total Sale], SAMEPERIODLASTYEAR(DateDimension[Date]))

Total Sale = SUMX(OrderArchive,OrderArchive[Total])

But what it returns it the toal sales for all years before ( my data contains from 2010) and not only 2015!

I tried DATEADD(xxx,-1,year) but still hetting same reults. what am I doing wrong ?

This is the data where comparing sales for each month per year

here is the reults of DAX as I mentioned above

Thanks in advance for looking this up

Hi 

I suggest u y not go withparallelperiod

Measure = calculate(sum(sales),parallelperiod(Date,-1,Year)

try this....

@iLikeAzureSQL these functions need context to work properly like in a table/matrix with a YEAR field

This is obviously not present in a Card!

So for a Card use something like this instead...

LY Sales =
CALCULATE (
    [Total Sale],
    FILTER ( 'Calendar', 'Calendar'[Year] = MAX ( 'Calendar'[Year] ) - 1 )
)
