Measure Monthly to diary.

[BMM27]

Hi, I have a measure [A] where it gives total monthly value. Additionally, I have a measure [B] that calculates the daily value by dividing [A] by the total number of days in the month. However, regardless of the month selected, [B] always returns the value for the last month.
What I want is a new measure that provides the sum of [B] for the selected date range.
Here are the different measures.

A =IF (

                [IsValid],

                CALCULATE ( SUM ( 'table'[valueA] ), table[valueB] = "C" ),

                BLANK () )

    )

B = 

VAR MonthlyValue = [A]

VAR SelectedMonth = SELECTEDVALUE('Calendar'[Month])

VAR SelectedYear = SELECTEDVALUE('Calendar'[Year])

VAR DaysInMonth = DAY(EOMONTH(DATE(SelectedYear, SelectedMonth, 1), 0))

RETURN

    IF(

        [IsValid],

        MonthlyValue / DaysInMonth,

        BLANK()

    )

Example with data.

For example, if I select the date range from February 1, 2024, to April 5, 2024, I expect the result to be:

If the daily value of feb is 5, march is 6 and apr is 7, the result would be 5*days in February(29)+6*days in March(31)+7*days in April(5 in that case). The result is 145+186+35=366

Any assistance would be greatly appreciated. Thank you!

Any help would be good, thanks!

Add a proper Calendar table to your data model and use a row count over that instead - much simpler.

I'm unsure about what you are referring to.
Here's what I currently have done:

I created a column in calendar and in myTable with mm-yyyy dates. And related both.
Then I created another column in myTable, it calculates daily price by month, 

dailyPrice = DIVIDE(CALCULATE(SUM(myTable[TotalMonthPrice]), myTable[sector] = "A"), DAY(EOMONTH(myTable[Date], 0)))

Next, a measure that counts number of days selected in the month of the record.

DaysCount = VAR month= MONTH(MAXX(myTable, myTable[Date]))

VAR year= YEAR(MAXX(myTable, myTable[Date]))

VAR min= FIRSTDATE(Calendar[Date])

VAR max= LASTDATE(Calendar[Date])

VAR selected= FILTER('Calendar',

                                'Calendar'[Date] >= min&&

                                'Calendar'[Date] <= max&&

                                MONTH('Calendar'[Date]) = month &&

                                YEAR('Calendar'[Date]) = year)

RETURN

    CALCULATE(

        COUNTROWS(selected),

        ALL(myTable),

        myTable[Date] = MAX('Calendar'[Date])

    )

Finally, I created a measure that gives me the daily sum from selected dates. However, if I select dates between two months, it always gives me the value of last month selected instead of the sum of all.

And always from day 1 to selected day, If i select 05-01-2024 to 10-01-2024 It gives me the value of 01-01-2024 to 10-01-2024 instead of 05 to 10.

PriceACC = SUM(myTable[dailyPrice]) * [DaysCount]

If i group by sector for example and I select dates between two different months, I want to calculate the sum of dailyPrice for each month.
For instance if I select from 20-01-2024 to 5-02-2024 I expect to multiply the sum of dailyPrice on january by 11 and on february by 5. However, my current measure, is only multiplying by 5 (last selected month).
Here's an example table:

Date	MM-YYYY	country	shop	sector	category	employee	totalMonthPrice	dailyPrice
01-01-2024	01-2024	A	1	R	33	A	310	10
01-01-2024	01-2024	A	2	T	44	B	290	29
01-02-2024	02-2024	A	3	T	33	C	290	29
01-02-2024	02-2024	B	1	R	44	D	290	29
01-03-2024	03-2024	C	2	T	33	E	310	31
01-03-2024	03-2024	A	3	R	44	F	310	31

Hi, It was a table, here I attached a .xlsx with some data.
 It is the result of multiplying 'SaleDaily' by 'DaysSelected'
The column SalesAcc is what I expect. When visualizing the data in a chart grouped by a certain key, 'SalesAcc' equals the sum of those values. Is the result of multiplying SaleDaily with DaysSelected. Take care, If i group by Key1, what I expect with SalesAcc is sum each value of different month and days month.
SaleDaily equals to TotalMonthSale Divided with number of days of its corresponding month, in that case January or February. 
DaysSelected is a measure that calculates the number of selected days for each month. I'm filtering from 02/01/2023 to 08/02/2023.

DaysSelected= VAR Month = MONTH(MAXX(Table, Table[Date]))

VAR Year= YEAR(MAXX(Table, Table[Date]))

VAR Datemin= FIRSTDATE(Calendar[Date])

VAR Datemax = LASTDATE(Calendar[Date])

VAR Selected= FILTER('Calendar',

                                'Calendar'[Date] >= Datemin&&

                                'Calendar'[Date] <= Datemax&&

                                MONTH('Calendar'[Date]) = Month&&

                                YEAR('Calendar'[Date]) = Year)

RETURN

    CALCULATE(

        COUNTROWS(Selected),

        ALL(Table),

        Table[Date] = MAX('Calendar'[Date])

    )

SaleDaily= DIVIDE(CALCULATE(SUM(Table[TotalMonthSales]), Table[Key6] = "RRR"), DAY(EOMONTH(Table[Date], 0)))

I hope this information is suficient for your undersanding. Link To Data

Hi, here is my solution, but It causes anther question:
My count selected days measure:

SelectedDays=

VAR Month= MONTH(MAX(Dim_Calendar[Date]))

VAR y = YEAR(MAX(Dim_Calendar[Date]))

VAR SelectedDate=

    FILTER(

        ALL(Dim_Calendar),

        Dim_Calendar[Date] >= MIN(Dim_Calendar[Date]) &&

        Dim_Calendar[Date] <= MAX(Dim_Calendar[Date]) &&

        MONTH(Dim_Calendar[Date]) = Month&&

        YEAR(Dim_Calendar[Date]) = y

    )

RETURN

    COUNTROWS(SelectedDate)

Daily Budget = (CALCULATE([Budget], STARTOFMONTH(Dim_Calendar[Date])) / DAY(EOMONTH(MIN(Dim_Calendar[Date]), 0))) * [SelectedDays]

What happens is if I put this on a table, the row of totals is wrong, same as if I put on a Card. Only when the data is with each month selected the data is perfectly correct. 

With a Card, maybe, I understand it a llittle but on a table, the totals it have to sum all the values but they don't.

I know this is because it's made with a measure, but I think this is only the solution.

If anyone knows how to solve this, I would appreciate it, thanks!

Solved!

Daily Budget = SUMX(VALUES(Dim_Calendar[Date]), (CALCULATE([Budget], STARTOFMONTH(Dim_Calendar[Date]))) / DAY(EOMONTH(MIN(Dim_Calendar[Date]), 0))) * [SelectedDays]
