Compare YTD to PYTD Sales by Week Numbers

[RAdams]

Hello All!!!

I've looked around a bit and haven't had much luck finding help on this. 

I have 2016 and 2017 Sales Data. I have InvoiceDate and Sales as my main columns. I'd like to be able to compare say Weekend Ending 3-25-17 to the comprabable Week Ending in 2016, which is 3-26-16. I am able to figure out how to get Week Number but I haven't been able to figure out a good way to use SamePeriodLastYear by week number. Or can I even use that?!?! 

Any suggestions/help/advice would be greatlly appreciated!

Thanks!

@CheenuSing Thanks for taking the time to share the link. I looked through a couple times and I'm still a bit confused. 

Should I use filters to compare Previous and Current Years? If so, how do I use Week Numbers in the filters? 

Thanks again for your time.

Build your calculations for this year and for last year. Then create a growth calculation: This year - Last Year.

After you create the totals it is a simple matter to put week numbers on rows or on the axis.

Total Sales = SUM(Sales[Line Sales])

Last Year Sales = CALCULATE([Total Sales], DATEADD(Date[Datekey], -1, year))

Growth = [Total Sales]-[Last Year Sales]

Make sure your report/page is filtered to the current year for the last year calculation to work. Then, if you would like, you can use your weeknumber as a filter as well. For example this week I would set my week number filter to be less than 15.

Awesome. A simple explanation is all I needed! I was way over complicating it!
