DAX Query for Current Year vs Previous Year Weekly Sales

Hi anilpoda ,

According to your description, here are my steps you can follow as a solution.

(1)  My test data is the same as yours.

(2) We can create two measures.

Current Year Weekly Sales =
CALCULATE (
    SUM ( Fact_OrderLines[Value] ),
    FILTER (
        ALL ( Fact_OrderLines ),
        YEAR ( [Order Date] ) = MAX ( 'Date'[Calendar Year] )
            && WEEKNUM ( Fact_OrderLines[Order Date] ) = MAX ( 'Date'[Week No] )
    )
)

Previous Year Weekly Sales =
CALCULATE (
    SUM ( Fact_OrderLines[Value] ),
    FILTER (
        ALL ( Fact_OrderLines ),
        YEAR ( [Order Date] )
            = MAX ( 'Date'[Calendar Year] ) - 1
            && WEEKNUM ( Fact_OrderLines[Order Date] ) = MAX ( 'Date'[Week No] )
    )
)

 (3) Then the result is as follows.
