Week over Week and comparison this year week to last year week

Hello Everyone


Please help!


I am starting my first PBI project.

But there are some problems.🤔😑


My customers want TABLES with


1. Sales by Week over Week and difference % comparison too /week comparing last week/


2. This year Week sales comparing Last year week sales and difference % as well. /2019.01st week comparing 2018.01st week.../


Are there any methods to show like that? Or it isnt possible to show like that in Power BI?🤔😐🙄😃

Hi @Anonymous 


Because there is no sample data I will try to describe the approach I would take.


Here I"m assuming your client wants everything in Table "Matrix"


Sales Week Over Week :


Make New Column of Week Num


WeekNum = WEEKNUM(Table-Date)


Now use this column with revenue/sales data to show sales by week. 

Please make sure to change Value -Sales to sum.


2. Calculate Same period last year


VAR DataMaxDate =
CALCULATE ( MAX ( 'GenIQ'[Date.Date].[Date] ), ALL ('GenIQ' ) )
VALUES ( 'GenIQ'[Date.Date].[Date] ),
DATESBETWEEN ( 'GenIQ'[Date.Date], BLANK (), DataMaxDate )
