Rolling Period

[kalpesh07]

Hi All,
I need help with Calculating on Rolling period Basis. MAT means last 12 Month.
So I've to calculate Sales% basis Last 12 month for every month like

Jan'24 MAT (Feb23-Jan24)
Feb'24 MAT (Mar23-Feb'24)
Mar'24 MAT (Apr23-Mar24)

I've already created a measure Sales% = Sales/Total sales.
How to create  MAT SALES% measure so whatever month is selected, it calculate basis last 12 month value.

Hi, @kalpesh07 

Thanks for @bhanu_gautam reply. Here is the complementary method, which still primarily utilizes the time-intelligent function.

Measure:

%Sales = 
VAR _dateEnd =
    SELECTEDVALUE ( 'Table'[Date] )
VAR _dateEndDay =
    DAY ( _dateEnd ) + 1
VAR _dateStart =
    EOMONTH ( _dateEnd, -13 ) + _dateEndDay
VAR _monthStart =
    EOMONTH ( _dateEnd, -2 ) + _dateEndDay
VAR _TotalSales =
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        'Table'[Date] >= _dateStart
            && 'Table'[Date] <= _dateEnd
    )
VAR _MonthSales =
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        'Table'[Date] >= _monthStart
            && 'Table'[Date] <= _dateEnd
    )
VAR _result =
    DIVIDE ( _MonthSales, _TotalSales )
RETURN
    _result

@kalpesh07 , You can achieve this by using DAX measures in Power BI

First make sure you have a date table in your model, if not than create one using 

DateTable =

    ADDCOLUMNS (

        CALENDAR (DATE(2020, 1, 1), DATE(2030, 12, 31)),

        "Year", YEAR([Date]),

        "Month", MONTH([Date]),

        "MonthName", FORMAT([Date], "MMMM"),

        "YearMonth", FORMAT([Date], "YYYYMM")

    )

Then create a sales measure

TotalSales = SUM(Sales[SalesAmount])

Then create a sales percentage measure

SalesPercentage = DIVIDE([TotalSales], CALCULATE([TotalSales], ALL(Sales)))

In Last create a new measure as Mat sales %

MAT Sales% =
VAR CurrentDate = MAX(DateTable[Date])
VAR StartDate = EDATE(CurrentDate, -11) -- 11 months back from the current month
RETURN
CALCULATE(
[SalesPercentage],
DATESBETWEEN(DateTable[Date], StartDate, CurrentDate)
)
