YOY Calculation with Date Filter

Hello,

 

I'm looking to create a table which has Profit, Last Year Profit, Count of Sales and Last Years Count.

 

I'm using SamePeriodLastYear however I want to use a date filter so I can select specific date ranges, for example the table below shows 1st May - 25th May however unless the filter includes dates from last year then the values are blank. 

 

Should I use something else apart from SamePeriodLastYear? 

 

 

Need Help

    Anonymous ,

    Prefer to create a date table and use that for time intelligence. Have a week, month year etc in the date table.

     

    sales =SUM(Sales[Sales Amount])

    Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-1,Year))

     

    YOY = [sales]- [Year behind Sales]

     

    YTD diff

    YTD QTY = TOTALYTD(Sum('order'[Qty]),'Date'[Date])
LYTD QTY = TOTALYTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year))
Previous Year = CALCULATE(SUM('order'[Qty]), PREVIOUSYEAR('Date'[Date]))


YTD QTY forced= 
var _max = today()
return
calculate(Sum('order'[Qty]),DATESYTD('Date'[Date]),'Date'[Date]<=_max)
//calculate(TOTALYTD(Sum('order'[Qty]),'Date'[Date]),filter('Date','Date'[Date]<=_max))

LYTD QTY forced= 
var _max = date(year(today())-1,month(today()),day(today()))
return
CALCULATE(Sum('order'[Qty]),DATESYTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALYTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)


YTD QTY forced= 
var _max = maxx('order',[Order date])
return
calculate(Sum('order'[Qty]),DATESYTD('Date'[Date]),'Date'[Date]<=_max)
//calculate(TOTALYTD(Sum('order'[Qty]),'Date'[Date]),filter('Date','Date'[Date]<=_max))

LYTD QTY forced= 
var _max1 =maxx('order',[Order date])
var _max = date(year(_max1)-1,month(_max1),day(_max1))
return
CALCULATE(Sum('order'[Qty]),DATESYTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALYTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)

// Year wise
This Year = CALCULATE(sum('order'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
Last Year = CALCULATE(sum('order'[Qty]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))

     

    To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :

    Appreciate your Kudos.

      Hi both amitchandak, TomMartens.

       

      Thanks for your replies, worked a treat! I was wondering whether there was a way to line up the days to match previous year as well.

       

      For example when I'm reporting this month it will be Friday the 1st of May however in 2019 the 1st of May is a Wednesday so I want to basically have the YOY report starting from Friday 3rd of May 2019 so I can compare like for like days too.

       

      Thanks,

       

      Mark

    Hey Anonymous ,

     

    this article https://www.daxpatterns.com/time-patterns/ contains almost everything about date-based calculations inside Power BI using DAX

     

    It will become necessary that you use a dedicated Calendar table (a best practice in Power BI data modeling). Here you will find an example of how you can create this table using DAX: https://github.com/sql-bi/DaxDateTemplate

     

    The steps you have to accomplish:

    1. Create a Calendar table
    2. Establish a 1-to-many relationship between the Calendar (the one-side) and your table (the many-side)
    3. Create two measures, one for the Last Year Profit and one for the Last Years Count.

    Hopefully, this provides what you are looking for to tackle your challenge.

     

    Regards,

    Tom
