## R12 Calculation Error

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'),
'Date Lookup'[Date],
1,
YEAR
) > SelectedMaxDate
)
)
Return
MinDate

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.
If I answered your question I would be happy if you could mark my post as a solution ✔️ and give it a thumbs up 👍
