Blank Year over Year Column

[mcornejo_1]

Hello,

I am relatively new to Power BI so I'm still fumbling through it.  I've tried to use a technique from another post, however, I continue to have an issue. As far as I can tell I have followed the steps correctly. I should be seeing 2015 results in the RevLastYear column next to 2016 as illustrated here but instead only get the Total 30107315 and that is only because I turned on Total row otherwise I have a blank RevLastYear column. I hope I provided enough information to give you an idea of what I'm up against here. Do you think you can help?

Year = YEAR(Shipments[Date])

DateMonth = MONTH(Shipments[Date])

SumRevenue = CALCULATE(SUM(Shipments[Total Revenue]))

RevLastYear = CALCULATE([SumRevenue],DATEADD(DATESYTD(Shipments[Date]),-1,YEAR))

Make sure your column Shipments[Date] is of type date value!

If you don't want to work with a separate date table and relate that table to your fact table you can still make it work by doing this instead:

Use Shipments[Date] directly in your visualization instead of using the calculations YEAR(..) and MONTH(...)

Power BI will create a date hierarchy for you automatically. 

Change the meassure for RevLastYear to: CALCULATE([SumRevenue],DATEADD(Shipments[Date].[Date],-1,YEAR))

That should give you what you are looking for.

Thank you all for your responses. I am able to wrap up my project now. Thiyags I did try to use SAMEPERIODLASTYEAR  but I was unable to get that to work either.

Hi @mcornejo_1,

You can use below formula to get the previous years' total.

Pervious Year Total =
var currDate=MAX([Date])
return
SUMX(FILTER(ALL(Shipments),Shipments[Date]>=DATE(YEAR(currDate)-1,1,1)&&Shipments[Date]<=DATE(YEAR(currDate)-1,12,31)&&MONTH([Date])=MONTH(currDate)),[Total Revenue])

Pervious Year(Month/Year) =
SUMX(FILTER(ALL(Shipments),Shipments[Date]>=DATE(MAX([Year])-1,1,1)&&Shipments[Date]<=DATE(MAX([Year])-1,12,31)&&[Month]=MAX([Month])),[Total Revenue])

Result:

Did you use SAMEPERIODLASTYEAR function? 

CALCULATE(SUM(Shipments[Total Revenue]),SAMEPERIODLASTYEAR(Shipments[Date ].[Date]))
