problem with calculation-many to many

hi

i have a problem with calculation of a measure

my final table looks like

Orig          Date               measureX

1            02/25/2017             2

1            03/04/2017             24

1            03/11/2017             223

1            03/18/2017             12

2            02/25/2017             250

orig=1 means weekly data, orig=2 means Rolling28 data

i want to have a slicer of date, and want to show the 4 related weeks. i.e if i select 2/25 on the slicer, the chart will show the 4 weeks on x axis and y will be the measure for each week.

the problem that i can't manipulate the data since the slicer sliced my table with 2/25 only (orig 1 and 2)

the solution here is many to many relationship with this table Rolling-Week:

Rolling          Week

2/25/2017      2/25/2017

2/25/2017      3/4/2017

2/25/2017      3/11/2017

2/25/2017      3/18/2017

3/4/2017         3/4/2017

3/4/2017         3/11/2017

3/4/2017         3/18/2017

3/4/2017         3/25 /2017 . . .. etc

but the problem is that there is no way to manage many to many relationship in power bi

so: i created the dates table: 

Date

2/25/2017

3/4/2017

 . . .

and connected it one to many with the rolling-week table from above.

now, if I slice on 2/25/2017, I know what are the 4 weeks related.

the problem is - calculated the measure for each week: MEASURE = 

CALCULATE (
sum'Final Table'[Measure X]),
(filter(ALL('Final Table'[week]),'FinalTable'[week]=max('Rolling-week'[Week]))
))

the problem is that i have to add an aggregation to the 'Rolling-week'[Week])

how can i calculaure the measure for EACH week?

thanks a lot
