Same Week Previous Month

Hi Expert

 

I am using Direct Query and trying to work out the same week previous month in Power BI. In my DimDate table i have Date, Year, WeekNum but not week ranking column. 

 

How would you do this... help please.

@Anonymous , You need new columns

 

 

Month Rank = RANKX(all('Date'),'Date'[Month Start date],,ASC,Dense)
Month Day = DATEDIFF('Date'[Month Start Date],'Date'[Date],Day)+1
min week start of month = minx(filter('Date',[Month Year] =earlier([Month Year])),[Week Start date])
week of month = datediff([min week start of month],[date],Week)+1

 

Measure
This Month = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Month Rank]=max('Date'[Month Rank])))
Last Month = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Month Rank]=max('Date'[Month Rank])-1))
MTD = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Month Rank]=max('Date'[Month Rank]) && [week of month] <=max([week of month])))
LMTD = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Month Rank]=max('Date'[Month Rank])-1 && [week of month] <=max([week of month])))
