## How to calculate measure for same period 2 years ago

Hi there,

I use SAMEPERIODLASTYEAR() to calculate measure for same period 1 year ago.

How do I do it for same period 2 years ago?

Thanks,

Wes

I Just found a better way to do it + It work dynamically based on user selection (not just on Only Year or Month or Days)

I've just nested Sameperiodlastyear

So for same period 2 year ago it will be like :

Syntax : SAMEPERIODLASTYEAR(SAMEPERIODLASTYEAR([Date]))

I tried the suggested PARALLELPERIOD function and it skewed dates and values. You can test by just comparing the calc field with one year only using SAMEPERIODLASTYEAR and PARALLELPERIOD.

What has worked for me was DATEADD, so, the mesuare will look like:

This way at least you compare the "same weekday", could be not in the same month but that is what I was after. Use @Anonymous but with DATEADD() suggestion below for other usecases.

I know is 5 yrs ago the question, but worth the contribution!

This was the one that worked for me!
My month selection in my slicer is dynamic, so this let me compare historical YTD numbers (parallelperiod would only give me prior full years)

Thanks!

Good to be mindful of what period type you have in your report.

If you want to see the whole of the year for two years ago then the  prior solution is perfect

calculate(measure, parallelperiod(datetable[date], -2, year))

However, if the report is a month by month one then try

calculate(measure, parallelperiod(datetable[date], -24, month))

Hi, I have tried your advice but I'm getting the error message below. Can you tell me what I'm missing? Thanks!

Are you missing the DATEADD function?

CALCULATE ([Net Sale TY], PARALLELPERIOD('Date'[Date], - 24,MONTH))

I think You need to include the PARALLELPERIOD function name and also a comma before the -24

Please let me know how you go
