Hi ApurvaKhatri
The trick is get an index calculated column to sort Weeks. (You can use power query)
This is the result
And the measures in my case are...
Total Sales = SUM(Sales[Sales])
Total Sales PW = var thisweek = FIRSTNONBLANK(Sales[Index];1) var prevweek = LOOKUPVALUE(Sales[Index];Sales[Index];thisweek-1) return CALCULATE([Total Sales];ALL(Sales[Date]);Sales[Index] = prevweek)
Variance = [Total Sales] - [Total Sales PW]
I hope this helps

Thanks for the solution. But in my case, sales is a measure so its not working
Hello BILASolution
In my case, Total Salea is a measure.
Will this solution still work?
Thanks,

Hi BILASolution and Ashish_Mathur
I cannot share the exact data.
But I would give you an idea hat I am trying to acheive
Table : Sample
Columns : PrincipalBalance (It is amount 1000, 24000, 32448, 767778) , Date (It contains everyday dates), Number(it has values negative, positive i.e 0.76, 0.4,-8.6, 75.0, 23, 5.4, 4.3 .... ), ID
I have created calculated column :
Day Of week = FORMAT ( Sample[Date], "dddd" ) - To extract the week day names from Date column
Date Select = if(Sample[Date] = "Wednesday",Sample[Date],Blank()) - I need the sum(PrincipalBalance) every wednesday for entire week starting Thursday to Wednesday. i.e 10/25/2017 - Wednesday sum(balance) from 10/19/2017 - 10/25/2017.
I have created measures:
Current = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number]< 1))
1-2 Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] < 3))
3-4 Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] < 5))
5+ Weeks = CALCULATE(COUNT(Sample[lD]),FILTER(Sample,Sample[Number] >= 5))
Sum = Current + 1-2 Weeks + 3-4 Weeks +( 5+ Weeks)
Data Display
Matrix
Rows: Date Select
Column: Months(Date)

Please Help.
Thanks alot for your time
Hi ApurvaKhatri,
No one here is intested in your actual data. Dummy your dataset and then share the result of that dummy dataset. The dataset that you paste here should be such that can be easily copied into an Excel file.
Hi,
Try this
=[Sales]-CALCULATE([Sales],FILTER(Calendar,MAX(Calendar[Table])-7)
I have assumed that the dates in your visual have been dragged from the Calendar Table. There should be a relatiosnhip between the Date column of your source data table and the date column of your Calendar table.
Hope this helps.
The date is a column from database
