Dax Same Period (user defined) Period Last Months

[Anonymous]

Hi everyone,

I need help to get the average of sales of past 3 months relative to the user defined day of the month (selectedvalue).

I am able to find similar solution but this always points to date TODAY(). 

For example, today is April 16, 2021:

- I would like to select April 20, 2021 (future date);

- Average of the following dates would be shown:

     March 1 - 20

     Feb 1 - 20

     Jan 1 -20

This is the similar solution i found and tried to edit by replacing TODAY() with SELECTEDVALUE:

=====

2-MonthSamePeriod Sum =

CALCULATE (

SUM ( 'Sheet 1'[Order Lines/Subtotal w/o Tax] ),

FILTER (

'DATE',

AND (

[Date]

>= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 1, 1 ),

[Date]

<= DATE ( YEAR ( TODAY () ), MONTH ( TODAY () ) - 1, DAY ( TODAY () ) - 1 )

)

)

)

Thanks in advance guys.

Hi @Anonymous ,

Please use the following measure to get the average of sales of past 3 months:

Measure =
AVERAGEX (
    FILTER (
        'Date',
        DATESINPERIOD ( 'Date'[Date], MAX ( 'Date'[Date] ), -3, MONTH )
    ),
    SUM ( 'Sheet 1'[Order Lines/Subtotal w/o Tax] )
)

@Anonymous Hey

Try this 

Test 2 = CALCULATE(SUM(Sheet1[Sales]),DATEADD(ALLSELECTED(Sheet1[Date]),-3,MONTH))

@Anonymous , Try a measure with help from date Table

Rolling 3 =
var _max = day(MAXX(ALLSELECTED('date'),'date'[Date])) //or // day(Today()) //or// Day(today()+4)
return
CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-3,MONTH), filter('Date', Day('Date'[Date]) <=_max))

//or are replacement values that you can use for _max
