Sameperiodlastyear custom hierarchy 4 weeks calendar.

Hi all, 

I need help with a custom hierarchy calendar. I have a 4 weeks per period calendar with 13 periods so 52 weeks each year. Uploaded test.pbix here for the simple sample data. https://1drv.ms/u/s!ArweH82sfYtEnHlOx78wkBU_I7Cu?e=HkxHzu 

I already made a small visual with the year,period,week values, but the previous year,period,week does not work. I can not use the previousyear function because of the custom calendar. 

 Compare withPY (measure)Expected PreviousYear
202120203738
P202011P20191123
W202044W20204401


In the table above you see that my PY (measure) gives me 37 where expected is 38 for the year 2021 compared with 2020. The PY (measure) gives me 2 where expected is 3 for the P202011 compared with P201911. The PY (measure) gives me 0 where expected is 1 for the W202044 compared with W201944. 

I think I just needs some custom hierarchy or something, but I need to have the "previous" year values for my period and weeks. 


Who could help me out?

Subtract 1 from the "current" year.  In your filter set the period filter to a replaced text value including the new year

 

Let's say the Period is P202011 and the year is 2020

so the code would look like

 

PY =

var p = max(Period)

var y = max(year)
return calculate(sum(value),Period = substitute(p,format(y),format(y-1))

Thanks for your reply, does not work the way I would like it to work, besides that the function FORMAT needs at least 2 arguments. 

I found a solution for the problem with the following measure: 

AMOUNT SPLY =
VAR HuidigJaar =
    MAX ( 'mdw DimDatum'[Jaar] )
VAR HuidigPeriodeNummer =
    RIGHT ( SELECTEDVALUE ( 'mdw DimDatum'[JaarPeriode] ), 2 )
VAR HuidigWeek =
    RIGHT ( SELECTEDVALUE ( 'mdw DimDatum'[JaarWeek] ), 2 )
VAR VorigJaar =
    FORMAT ( HuidigJaar - 1, "0000" )
VAR VorigPeriodeNummer = "P" & VorigJaar & HuidigPeriodeNummer
VAR VorigWeek = "W" & VorigJaar & HuidigWeek
VAR Result =
    IF (
        SELECTEDVALUE ( 'mdw DimDatum'[JaarWeek] ) <> BLANK (),
        CALCULATE (
            [Amount],
            FILTER (
                ALL ( 'mdw DimDatum' ),
                'mdw DimDatum'[JaarWeek] = VorigWeek
                    && 'mdw DimDatum'[JaarPeriode] = VorigPeriodeNummer
                    && 'mdw DimDatum'[Jaar] = VorigJaar
            )
        ),
        IF (
            SELECTEDVALUE ( 'mdw DimDatum'[JaarPeriode] ) <> BLANK (),
            CALCULATE (
                [Amount],
                FILTER (
                    ALL ( 'mdw DimDatum' ),
                    'mdw DimDatum'[JaarPeriode] = VorigPeriodeNummer
                        && 'mdw DimDatum'[Jaar] = VorigJaar
                )
            ),
            IF (
                SELECTEDVALUE ( 'mdw DimDatum'[Jaar] ) <> BLANK (),
                CALCULATE (
                    [Amount],
                    FILTER ( ALL ( 'mdw DimDatum' ), 'mdw DimDatum'[Jaar] = VorigJaar )
                ),
                CALCULATE (
                  [Amount],
                    ALL ( 'mdw DimDatum' )
                )
            )
        )
    )

RETURN
    Result


I only have one problem now, I would like to add some timeintelligence like WeekToDate, PeriodToDate and YearToDate. But then I do not get the cumulatives. 

If you have a custom calendar you need to create custom time intelligence functions. They will be especially hairy across year boundaries.
