Aha, I see what is happening

 

Want to give this a test?  I've highlighted the function to change in red.  Let me know how it goes

 

Sum of Last Three Months = 
		SUMX(
				DATESINPERIOD(
					Dim_Calendar[Date],
					DATEADD(STARTOFMONTH('Dim_Calendar'[Date]),-3,MONTH),
					3,
					MONTH),
					[Total Amount]
		)

Hello Phil_Seamark

 

Now it is working as expected for Case A.

    Hi mrslyfox

     

    I think it might be a case of just tweaking the date ranges.  eg. the -3 to -2 as I have highlighed in red

     

    Sum of Last Three Months inc current = 
		SUMX(
				DATESINPERIOD(
					Dim_Calendar[Date],
					DATEADD(STARTOFMONTH('Dim_Calendar'[Date]),-2,MONTH),
					3,
					MONTH),
					[Total Amount]
		)
