Today compared to same day last year

Hi everyone,

 

I have a measure showing order value for today:

 

OrderValueToday = CALCULATE(SUM(PostedSalesInvoices[Amount]);PostedSalesInvoices[Order_Date] = TODAY())
                                  +
                                  CALCULATE(SUM(SalesOrderList[Amount]);SalesOrderList[Order_Date] = TODAY())
 
I wish to show a measure showing the order value for same day last year. For this I will only have one transaction table [PostedSalesInvoice] and I wish to filter on order date last year. I have tried with SAMEPERIODLASTYEAR and PREVIOUSYEAR (+ filter on today's date) without any success. 
 
Any suggestions?
 
Thanks!
 
Lisa

Re: Today compared to same day last year

Hi @LisaB,

 

I suppose that PostedSalesInvoice table is connected to the calendar table by posting date. You can either change the relationship by connecting to the order date or you can create a new inactive relationship between calendar date and order date.

Then you can write a measure as below:

 

OrderLY =
CALCULATE (
    CALCULATE (
        SUM ( PostedSalesInvoices[Amount] ),
        USERELATIONSHIP ( PostedSalesInvoices[Order_Date], CalendarDate[Date] )
    )
        + SUM ( SalesOrderList[Amount] ),
    SAMEPERIODLASTYEAR ( CalendarDate[Date] ),
    CalendarDate[SameDayLY] = TRUE ()
)

I hope you can solve now!

Re: Today compared to same day last year

Hi @LisaB

 

Do you have Calendar table in your Model? If not, please create a calendar table and then you can try this DAX:

 

LastYear Numbers = CALCULATE(SUM(Sales_Fact.Sales),DATEADD(Dates[Date],-1,YEAR)

 

Thanks

Re: Today compared to same day last year

Hi @LisaB,

 

You can create a calculate column in Calendar Dimension:

 

SameDayLY= 
var TodayDate = TODAY()
var LastYear = YEAR(TodayDate)-1
var LastMonth = MONTH(TodayDate)
var LastDay = DAY(TodayDate)
return
'Calendar'[Date]= DATE(LastYear,LastMonth,LastDay)

Then a measure:

 

OrderValueSameDayLY = CALCULATE(SUM(PostedSalesInvoices[Amount]);CalendarDate[SameDayLY]=TRUE()) 
                                  +
                                  CALCULATE(SUM(SalesOrderList[Amount]);CalendarDate[SameDayLY]=TRUE())

Regards

Chiara

Re: Today compared to same day last year

 Hi @rajendran and @Chiara,

 

Thank you for your replies.

 

I've got a calendar table.

 

With the first formula (rejendran) I get the value for the whole month last year. How can I add the filter on order date = samedayLY?

 

With the second formula I didn't get anything at all. 😕

 

Worth to mention is that I have a report level filter date on this month.

 

Thanks!

Re: Today compared to same day last year

After calculate column samedayLY try this measure:

 

OrderLY= CALCULATE[OrderValue], SAMEPERIODLASTYEAR(CalendarDate[Date]), CalendarDate[samedayLY] = TRUE())

Re: Today compared to same day last year

Hi @Chiara,

 

Thanks - that formula gives me a value now. However, not the value I'm looking for.

 

In my PostedSalesInvoice table, I have two dates, posting date and order date. It might be that an invoice has been posted after the order date, i.e. order date = 2018-01-29 but posting date = 2018-01-31.

 

I want to show the values filtered on order date = same date LY. Now it gives me the value of posting date = same date LY.

 

Hope this makes sense.

Re: Today compared to same day last year

Hi @Chiara,,

Thanks for your solution it helped me a lot in a similar case that needed SameDayLY calculated column but your way returned a true value for "2019-03-01" if Today date was a Leap day for example "2020-02-29" but that was a wrong behavior according to my business requirements so I handled it as follow:

SameDayLY =
var TodayDate = TODAY() // "2020-02-29"
var TodayYear = YEAR(TodayDate)
var LastYear = YEAR(TodayDate)-1
var LastMonth = MONTH(TodayDate)
var LastDay = DAY(TodayDate)
return
IF ( MOD(TodayYear,4) = 0 && LastMonth = 2 && LastDay =29 , FALSE() , 'Calendar'[Date]= DATE(LastYear,LastMonth,LastDay))

Regards;
