MDXScript(Model) calculation Error

I am trying to create a simple moving average for my area chart and I keep getting the following error. "A column specified in the call to function 'datesbetween' is not of type date. this is not supported."

 

Here is my function

AVERAGEX(
DATESBETWEEN('Data (10)'[RequestDateRaised - Copy], MAX('Data (10)'[RequestDateRaised - Copy]), max('Data (10)'[RequestDateRaised - Copy])),
CALCULATE(sum('Data (10)'[Count]))
)
Need Help

    Hi Anonymous ,

     

    I suggest you to create a DimDate table with continuous date if you want to use DATESBETWEEN() which is a time intelligence function.

    Try CALENDAR() or CALENDARAUTO().

    DimDate = ADDCOLUMNS( CALENDARAUTO(),"Year",YEAR([Date]),"Month",MONTH([Date]))

    My Sample:

    Measure:

    Measure = 
AVERAGEX(
DATESBETWEEN(DimDate[Date],MIN(DimDate[Date]),MAX(DimDate[Date])),
CALCULATE(sum('Data (10)'[Count]))
)

    Then add Year/Month columns into Axis. Result is as below.

    Anonymous , Make sure the data type is date, why both are max

    always use date table

    try like

     


    CALCULATE
    ( AVERAGEX(values('Data (10)'[RequestDateRaised - Copy]),
    CALCULATE(sum('Data (10)'[Count]))
    ),DATESBETWEEN('Date'[Date],min('Date'[Date]),max('Date'[Date])))

    To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :radacad sqlbi My Video Series Appreciate your Kudos.

    Hello, that still didn't work. I did not get an error in DAX but when I input the measure in my chart it did not add a simple moving average (SMA).
