harirao I'm assuming you have a DimDate table??
If not, get one, they make a big difference:

Once you have the date table, I would consider a slightly different approach to this problem, using time intelligence to change the filter context within the measure, rather than creating a calculated column for previous period.
So something like:
Trend =CALCULATE([%6week_1&2], DATEADD(DimDate[Date], -7, DAY))No need to mess with region as that will come automatically from the context of the matrix.harirao A small update:In the slicer, either use the:DimDate[Date] ,DimDate[ReportWeek]DimDate[Week]Basically anything from the DimDate table NOT the Query1[reportdate]harirao , refer to my blog on how to work with the week; this week vs last week etc.
To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
