Calculate running count of months between two dates

[MohanVanks]

Hello All,

I am trying to calculate the running count of months selected between two dates using relative date filter.

I have used below dax which gives me the running count of months between two dates 

MonthCount = 
 CALCULATE (
    
COUNTROWS(VALUES(VW_Supplier_Scorecard[yrmnth_nw])),
 FILTER (
 ALLSELECTED(VW_Supplier_Scorecard),  
 'VW_Supplier_Scorecard'[yrmnth_nw] <= MAX(VW_Supplier_Scorecard[yrmnth_nw])
 )
)

But In my same report, i need to have month year filter as well where i could able to filter month wise.

Now when i filter from Year Month slicer,  then it is giving me only that month count.

But i am expecting the running count value should be returned.

Here I have filtered Nov 22, it is returning 1, but i am expecting it to return as 15.

Can anyone help me please.

Thanks,

Mohan V.

@MohanVanks , with help from date table

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(all('Date'),'Date'[date] <=max('Date'[date])))

Cumm Sales = CALCULATE(SUM(Sales[Sales Amount]),filter(allselected(date),date[date] <=max(date[Date])))

or window function

@amitchandak i tried the dax which you given using date master table, but it gives the running count of year-month column 

VAR minDate =
    CALCULATE (
        MIN ( 'DateMaster'[Date] ),
        ALLSELECTED( 'DateMaster' )
    )
RETURN
    CALCULATE (
        DISTINCTCOUNT(DateMaster[Year Month]),
        FILTER (
            ALL ( 'DateMaster' ),
            'DateMaster'[Date] >= minDate
                && 'DateMaster'[Date] <= MAX ( 'DateMaster'[Date] )
        )
    )

But when i filter with Year month, then it gives the same result as above in my ask as 1.

Can you please help me here.

@amitchandak thanks for the reply.

In my case, i do not have any date table, and i shouldnt be using it for some reasons.

Can you please suggest/guide me for the same without date table.
