R12 Calculation Error

[Mikail]

Hello everyone, I am trying to calculate R12 for past 5 years. I am filtering my data based on Date lookup table. The max or latest date is 01/07/2021(dd/mm/yyyy). When I choose this latest date(July) from slicer I was expecting to see 01/08/2020. However calculation returned just blank. However when I choose  June calculation is correct. Is there anyone to help to solve the issue?

The Dax Code:

R12 IND =

Var SelectedMaxDate = MAX ('Date Lookup'[Date])

Var MinDate =

CALCULATE (

MIN ( 'Date Lookup'[Date]),

FILTER (

ALL ('Date Lookup'),

DATEADD (

'Date Lookup'[Date],

1,

YEAR

) > SelectedMaxDate

)

)

Return

MinDate

Thanks in advance!

Hey @Mikail ,

I'm not really sure if the approach makes sense as DATEADD just changes the dates in the column. I think what you are looking for is the function DATESINPERIOD. Try the following approach:

R12 IND =
VAR SelectedMaxDate = MAX( 'Date Lookup'[Date] )
VAR MinDate =
    CALCULATE(
        MIN( 'Date Lookup'[Date] ),
        DATESINPERIOD(
            'Date Lookup'[Date],
            SelectedMaxDate,
            -1,
            YEAR
        )
    )
RETURN
    MinDate

If you need any help please let me know.
