Need to calculate dax in which Total sum of Month should be constant for all the days.

[PrathameshM]

I need to create a measure to calculate all month's data. 

E.g. Need to create logic based on the measure column 

Month	Days	Sales	Measure
Jan	1	10	40
Jan	2	20	40
Jan	3	10	40
Feb	1	10	60
Feb	2	20	60
Feb	3	30	60

@PrathameshM - You can use the DAX Measure below:

VAR selected_month =
    SELECTEDVALUE ( 'Table'[Month] )
RETURN
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        FILTER ( ALL ( 'Table' ), 'Table'[Month] = selected_month )
    )

If this works, please mark it as the solution.

What if we want to calculate the YTD based on the financial year?

Hi @PrathameshM ,

Your solution is great, @mark_endicott . It worked like a charm! Here I have another idea in mind, and I would like to share it for reference.

So easy!

Please try:

Measure = CALCULATE(
     SUM('Table'[Sales]),
     ALLEXCEPT('Table','Table'[Month])
)

The page effect is as shown below:

pbix file is attached.

If you have any further questions please feel free to contact me.
