Issue with using "# of Months Complete" to do a calculation

[kressb]

I need to take Total Amount for a Year, Divided by a Base to get a Calculation (the measure).
It must flex with each year, so for this year, it must prorate the Calculation since the year is not complete.
Desired Result:

My issue is there is not always an "amount" for every month of the year, but I need it to divide by the total # of months completed regardless.

Ex - "Amounts" table:

Fiscal Year 2020: "Nineteen" only had data for April, May, and June.

       I still need it to calculate as 12 Mons Total / 12 Mons Complete, but 
       Var _Num = DistinctCountNoBlank(Amounts[MonthYr])

            -- > only returns 3

        Var _Num = Calculate(DistinctCountNoBlank(Amounts[MonthYr]),Allselected())

           --> Returns total from Fiscal Year 2020 and Fiscal Year 2021

How do I return the maximum count regardless as to if that Name as a value for all months?
I wanted to do something like:

  Var _Num = Calculate(DistinctCountNoBlank(Amounts[MonthYr]),Allselected(),Filter(Amounts,Amounts[Fiscal Year]=Earlier(Amounts[Fiscal Year])
    but I can't use Earlier in a Measure Context...

Hi, @kressb 

You can change 'earlier' to 'selectedvalue' in measure.

The result you want to get is not 3 or 8. What should the result be? It’s not difficult, you just need to make it clear what you want, but I’m a little confused from your description. So if you still can't get the correct result after modifying the code, please explain it again, we can help you soon.

@v-janeyg-msft apologies:
For 2020 - instead of 3, I need 12.

For 2021 - I need 9 

If both 2020 and 2021 are selected or a "Total" Column is shown: 21 (12+9)

(Month Complete of the "Desired Table")

I tried 
Var _Num =  Calculate(DistinctCountNoBlank(Amounts[MonthYr]),
                                     Filter(AllSelected(Amounts),Amounts[Fiscal Period]=Max(Amounts[Fiscal Period]))
                                      )
This works perfectly to display the columns the problem is if I want to see a "Total".

It only gives the months for the max Fiscal Period (2021, which is through 9 months) rather than adding 9+12 = 21.
It makes sense that is the result since that is what I have written, but I don't know how to fix it..

**update:
Var _Num = Calculate(DistinctCountNoBlank(Amounts[MonthYr]),
                                     Filter(AllSelected(Amounts),Amounts[Fiscal Period]=(Amounts[Fiscal Period]))
                                      )
works perfectly for the "Total" but not for the individual Year Columns.

Is there some way to get both to work in the same measure? is it impossible?

@v-janeyg-msft @amitchandak @Jihwan_Kim any ideas? I'm desperate 

[v-janeyg-msft]

Hi, @kressb 

I'm back. I will help you but I still need more information, the data() you provided don't show 'Amounts[MonthYr]' column, I can’t see how many there are so I don’t know how 12+9 is calculated. If there is no logic, You can define it manually. If has, please share more data for reference.

Amounts[MonthYr] is the "Date" column here:

I just accidently labeled it differently in the picture.

[v-janeyg-msft]

Hi, @kressb 

In your picture, I only can see 'fiscal period in 2020' has 2 months and 'fiscal period in 2021' has 5months. I have asked you, but you didn't tell me why the result of 12+9 occurred.

If you have no logic, you can directly define it manually:

measure =
SUMX (
    SUMMARIZE (
        Amounts,
        "a", IF ( SELECTEDVALUE ( 'Amounts'[Fiscal Period] ) = "2020", 9, 12 )
    ),
    [a]
)

 Or try to modify it?

If it doesn't solve your problem, Can you share some complete data that we need to know about the calculation results?

@kressb , with help from date table

This year Sales = CALCULATE(DistinctCountNoBlank(Amounts[MonthYr]),DATESYTD(ENDOFYEAR('Date'[Date]),"12/31"))/12
Last year Sales = CALCULATE(DistinctCountNoBlank(Amounts[MonthYr]),DATESYTD(ENDOFYEAR(dateadd('Date'[Date],-1,Year)),"12/31"))/12

//Only year vs Year, not a level below. But with independent table

This Year = CALCULATE(DistinctCountNoBlank(Amounts[MonthYr]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])))
Last Year = CALCULATE(DistinctCountNoBlank(Amounts[MonthYr]),filter(ALL('Date'),'Date'[Year]=max('Date'[Year])-1))

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.
