I want to show comulative count month and year wise.

[Muhammadusman12]

I want to sum the previous month with the current month dynamically.

For example : Feb=100 , jan = 10 ,march = 20 result on march ( current month ) should be march + jan + fed = 130.

This is the appropriate measure for tackling this. 

Running Total =

CALCULATE (

    COUNTROWS ( Sales[SalesAmount] ),

    FILTER (

        ALL (Sales),

        Sales[DateKey] <= MAX ( Sales[DateKey] )

    )

)
