Custom Financial Year

[Anonymous]

Hi,

Our financial year runs from Jun 1st to May 31st is there an 'easy' way to create a new column in the calendar table which has the relvent year against the date.

In our nominal detail table it has financial year.  What would be the best way to get 

Year to Date

Same period Last year

Variance against last year

An example of previous year variance is

Previous Year Test = CALCULATE(sum('public nomhead'[nominal]),'public nomdet'[nom_year] = ('public nomdet'[nom_year] -1))

The above doesnt work though... all help appreciated.

Thanks

Chris

you can specify custom financial year in the calculation
https://docs.microsoft.com/en-us/dax/datesytd-function-dax
you will need custom column in your calendar table

FinancialYear = 
VAR __month = MONTH('Calendar'[Date])
VAR __year = YEAR('Calendar'[Date])
RETURN
IF(__month<6, __year-1 & "/" &__year, __year & "/" & __year+1)

SAMEPERIODLASTYEAR will work fine whenever you select year from this

as for YTD, you can use DATESYTD, e.g.

YTD = 
CALCULATE(
    SUM('public nomhead'[nominal]), 
    DATESYTD(Calendar[Date], "31-05")
)

for PY YTD you can just use SAMEPERIODLASTYEAR within calculate that uses the [YTD] measure

Thanks @Stachu

All works great Apart from previous year to date.

I have

Debit YTD prev year = CALCULATE(sum('public nomdet'[debit]),SAMEPERIODLASTYEAR(DATESYTD('Calendar'[Date],"05/31")))

Example

in 2018/2019 it only seems to do the year to date where there is a value in 2018/2019 rather than the months where are no values but values in 2017/2018

I set the direction in the relatio bship betwen the calendar and fact table as one way as per other forum post and it seems to work.

Strange... would be useful to know why

I always try to keep them with single direction as it makes DAX more predictable, here is some explanation on bidirectional relationships in general
