    Hi Sowmiya,

     

    I have made a test with your scenario. 

     

    You could create an calendar table and then create the measure below.

     

    Measure =
VAR selectweek =
    SELECTEDVALUE ( 'Table'[WeekNum per Month] )
VAR current_month =
    SELECTEDVALUE ( 'Table 2'[Month] )
VAR previous_month =
    IF ( current_month = 1, 12, current_month - 1 )
VAR YearNo =
    IF (
        current_month = 1,
        SELECTEDVALUE ( 'Table 2'[Date].[Year] ) - 1,
        SELECTEDVALUE ( 'Table 2'[Date].[Year] )
    )
RETURN
    CALCULATE (
        SUM ( 'Table'[Sales] ),
        FILTER (
            ALLSELECTED ( 'Table' ),
            'Table'[Date].[Year] = YearNo
                && 'Table'[Date].[MonthNo] = previous_month
                && 'Table'[WeekNum per Month] = selectweek
        )
    )

    More details, please refer to my test pbix.

     

    Best Regards,

    Cherry

I want to find Sales for Same Week the Previous Month.
For Example, my current day date is jan 10, 2019. 
My Current Week Number is 2.

Sales Output Expected for:
Previous Month date is dec, 2018.
Same Week Number is 2.
Have to find Sales for Week 2 for Dec 2018.

Current Date is Dynamic, Based on that Previous Month Same Week Sales has to be found. Is this Possible?

That means the 2nd week of December 2018 is actually Week No. 49.

 

Correct ????

If Yes, then it seems to be possible. I will update you.
