context and calculation

[ccc123]

I have 2 sales files Aw and Aw-1, with 1 week of difference. I want to measure the evolution. In a visual matrice in the data report, I used a hierarchy coming from Aw. When I want to catch up the Sales of previous week (file Aw-1, which is built identical as Aw), for each row I have the total of sales previous week and not the detail
How can I have the sales of previous week ?

Hi @ccc123 ,

I create the following relationship.

Then create these measures:

W = CALCULATE ( SUM ( Aw[Sales] ), USERELATIONSHIP ( Aw[Date], Dates[Date] ) )

W-1 = 
CALCULATE (
    SUM ( 'Aw-1'[Sales] ),
    FILTER (
        'Aw-1',
        'Aw-1'[Product] = MAX ( Aw[Product] )
            && 'Aw-1'[Sub_Product] = MAX ( Aw[Sub_Product] )
    ),
    USERELATIONSHIP ( Dates[Date], 'Aw-1'[Date] )
)

Measure = IF ( [W] = BLANK (), [W-1], [W] )

If the problem is still not resolved, please provide detailed error information or the expected result you expect. Let me know immediately, looking forward to your reply.
Best Regards,
Winniz
