    Maybe this:

     

    Rolling 3 Month Total =
CALCULATE (
    KPI_Finance_Actual_Budget[Actual Profit],
    DATESINPERIOD (
        KPI_Finance_Actual_Budget[FullDate],
        LASTDATE ( PREVIOUSMONTH ( KPI_Finance_Actual_Budget[FullDate] ) ),
        -3,
        MONTH
    )
)

    Although if "KPI_Finance_Actual_Budget[FullDate]" doesn't have a consecutive range of all dates you may get some strange results.  Best to use a separate calendar table.

If you happen to have a problem with consecutive days , you can use the solution below leveraging month numbers in your calendar dimension.

= CALCULATE(
    [Sales Amount],
    FILTER(
        ALL('Date'),
        'Date'[Month Number] > MAX('Date'[Month Number]) - 4
               && 'Date'[Month Number] <= MAX('Date'[Month Number])-1
   ) , VALUES('Date'[Calendar Year])
)
