Community SupportHi cham ,
You may try to create measures like DAX below.
MaxWeekNumber = CALCULATE(MAX('Calendar'[WeekNum]), FILTER(ALL('Calendar'), 'Calendar'[Year]=MAX('Calendar'[Year)))
Previous Week =
VAR CurrentWeek = SELECTEDVALUE('Calendar'[WeekNum])
VAR CurrentYear = SELECTEDVALUE('Calendar'[Year])
VAR Filter=IF(CurrentWeek = 1, FILTER(ALL('Calendar'), 'Calendar'[WeekNum] =MAXX('Calendar', [MaxWeekNumber] ) && 'Calendar'[Year] = CurrentYear - 1), FILTER(ALL('Calendar'), 'Calendar'[WeekNum] =CurrentWeek - 1 && 'Calendar'[Year] = CurrentYear))
RETURN
IF(ISBLANK([%GP]), BLANK(), SUMX(Filter, [%GP]))
If I misunderstood it, could you please share your sample data and desired output screenshots for further analysis? You can also upload sample pbix to OneDrive and post the link here. Do mask sensitive data before uploading.
Best Regards,
Amy
