Create a table with lastyear sales

[reynaldo_malave]

Hi Guys,

I am Trying to create a table for last years sales by day of the week and week of the year. For example: today june 21st 2021 is the 25th week´s monday. I am looking for the sales made on June 15th 2020. 

Thanks,

Reynaldo

@reynaldo_malave , I am assuming you are looking for last year same week day sale

That is usually 364 days behind , with help from date table

Week Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd('Date'[Date],-364,Day))

Add week related  column in your date table

Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format

Then you can try

measures
This Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])))
Last Week = CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=max('Date'[Week Rank])-1))
Last year Week= CALCULATE(sum('order'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]=(max('Date'[Week Rank]) -52)))
