DAX for two Date Keys in one table

[hitesh1607]

Hi - I do have a Power BI model with ShipDateKey (Active) and OrderDateKey (Inactive) for fct Sales joined with DimCalendar. I am looking for a DAX calculation that gives me SUM of GrossPrice where ShipDateKey is Current Month ( Jan 2021) AND Order Date is (Dec 2020).

I also have DimCalendar with Column RelativeMonth (-1,0,1) as 0 Previous Month and 1 as Current Month.

The SQL for the calculation should be like this. 

SELECT SUM([Gross Price]) GP
FROM [DW].[dbo].[v_fctSales]
WHERE OrderDateKey LIKE '202012__' AND ShipDateKey LIKE '202101__'

Measure =
VAR Y1_ =    YEAR ( TODAY () )
VAR M1_ =    MONTH ( TODAY () )
VAR Y0_ =    YEAR ( EDATE ( TODAY (), -1 ) )
VAR M0_ =    MONTH ( EDATE ( TODAY (), -1 ) )
RETURN
    CALCULATE (
        SUM ( Sales[Gross Price] ),
        YEAR ( Sales[ShipDateKey] ) = Y1_,
        MONTH ( Sales[ShipDateKey] ) = M1_,
        YEAR ( Sales[OrderDate] ) = Y0_,
        MONTH ( Sales[OrderDate] ) = M0_
    )

Hi @hitesh1607 

Measure =
CALCULATE (
    SUM ( Sales[Gross Price] ),
    YEAR ( Sales[ShipDateKey] ) = 2021,
    MONTH ( Sales[ShipDateKey] ) = 1,
    YEAR ( Sales[OrderDate] ) = 2020,
    MONTH ( Sales[OrderDate] ) = 12
)

Hi @AlB - This way my DAX will become static and I need a dynamic solution that can determine the Current Month for the Ship date and the previous month for the Order Date. Is there a way we can write a DAX using relative Calendar month ?? I Do have that in my dimCalendar and it changes dynamically.
