Need Last Week data using DAX
Hi ,
I have a data of showing day wise incidents (ticket). We are maintaining this things in excel sheet. My Requirement is to show the last weeks data (not last 7 days).
Can someone help how do we write the formula to get the last week data. Day begins from Mon to Sun.
Thanks,
Sudharshan
Hi Sudharshan1919 ,
If you just want to compare data from the same year:
Measure = CALCULATE ( SUM ( 'table'[value] ), FILTER ( ALLSELECTED ( 'table' ), YEAR ( 'table'[date] ) = YEAR ( MAX ( 'table'[date] ) ) && WEEKNUM ( 'table'[date], 2 ) = WEEKNUM ( MAX ( 'table'[date] ), 2 ) ) )If you just want to compare data across years, you will need to create a year_week column then create a rank column based on it.
year_week = YEAR('table'[date])*100+WEEKNUM('table'[date],2) _rank = RANKX('table','table'[year_week],,ASC,Dense)Measure = CALCULATE ( SUM ( 'table'[value] ), FILTER ( ALLSELECTED ( 'table' ), 'table'[_rank] = MAX ( 'table'[_rank] ) - 1 ) )Best Regards,

Sudharshan1919 This is easiest if you create a Sequential week column. Then you don't have to worry about years and years having 52 or 53 weeks in them.
