calculate row count of each year of rolling return years

[ak77]

Hi All,

i hve the below requirement, please check. i have below large dataset with following columns from 2010 till date.some code has data daily wise(365 rows per year) 

and some both monthly and daily  data (12 and 365 rows per year) 

Code,Class name, returns, Date

i am calculating rolling periods( 1 year, 2year till 10 year as below pic) for each code and date selected(Only month end date selection) and its working fine.

My client is asking me to calculate rolling periods if the rowcount matches 365/year for day wise data and 12/year for monthly data.

for ex: for Code 1  from 2022 its daily data and before 2022 ->Monthly data

For 31-dec-2022 and Code 1 selected

1 year(2022)-> check for 365 rows for 2022 year

2 yr 2022,2021 check for 365 rows for 2022 year+ check for 12 rows for 2021 year

3 yr 2022,2021,2020 check for 365 rows for 2022 year+ check for 12 rows for 2021 year+ check for 12 rows for 2020 year

if the rowcount matches then calculate sum of all selected years else display blank.

Please help

How to use a generic way condition to implement this rule

@ak77 , Using date table you can create measures like 

Rolling 1 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-1,Year))

Rolling 1  = CALCULATE([Net], WINDOW(-11,REL, 0, REL, ADDCOLUMNS(ALLSELECTED('Date'[Month Year],'Date'[Month Year Sort] ),ORDERBY([Month Year Sort],asc)))

or

Rolling 2 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-2,Year))

Rolling 2  = CALCULATE([Net], WINDOW(-23,REL, 0, REL, ADDCOLUMNS(ALLSELECTED('Date'[Month Year],'Date'[Month Year Sort] ),ORDERBY([Month Year Sort],asc)))

Create all measures, and if needed add them to calculation groups
