Same Period Last Year

Hi PBI Community,

I need some help with DAX Time Intelligence.

I am writing a DAX function that uses the sameperiodlastyear function on the calendar date to evaluate the total percentage in the 1 year period.

For example, the table A contains the percentages on Calendar_Date level and it is Fiscal Year 2021 data.

Fiscal Year 2021
Calendar_DatePercentage
10/4/20201.50%
10/5/20202.60%
10/6/20203.70%
10/7/20204.80%
10/8/20205.50%
10/9/20205.40%
10/10/20202.30%


I am writing a DAX function for Fiscal Year 2022 as below to :
Previous_Year_Percentage = CALCULATE([Percentage], Sameperiodlastyear(DATE[Calendar_Date]),ALLEXCEPT(Date,[Calendar_Date])

I am getting the below output from the above DAX statement : 

Fiscal Year 2022
Calendar_DatePercentage
10/3/20212.20%
10/4/20211.50%
10/5/20212.60%
10/6/20213.70%
10/7/20214.80%
10/8/20215.50%
10/9/20215.40%


The issue with the output is it takes 2.20% which is not part of the Fiscal Year 2021 and instead the output should start with 1.50% on 10/3/2021 and so on.

Like below : 

Fiscal Year 2022
Calendar_DatePercentage
10/3/20211.50%
10/4/20212.60%
10/5/20213.70%
10/6/20214.80%
10/7/20215.50%
10/8/20215.40%
10/9/20212.30%


I would appreciate any help on this.

Thanks,
Deepak

  • Hi Pat,

    Thanks for responding.

    I was able to resolve this using the below logic :

    CALCULATE([Percentage],
    DATEADD(Calendar_Date,-[Previous_Year_Calendar_Day_Count],DAY),
    ALLEXCEPT(Date,[Calendar_Date])

    -[Previous_Year_Calendar_Day_Count] moves the calendar days of current fiscal year to exact number of days based on previous year count.This helped in overlapping the fiscal year start date.

    Thanks,

    Thanks,
    Deepak

    Are you using MMDD or DDMM? Either way, instead of using time intelligence functions, one way would be to add Fiscal Year and a Day (or Month) of Fiscal Year columns to your Date table. You could then write a measure that moves the context to the previous Fiscal Year on the same Day of the the Fiscal year.
