Last week Dax

[gsulaimon]

Dear All, 

I have this formula below to calculate period in date for weeks but it keeps bringing the wrong data 

Last week = CALCULATE([PPE Lsum], DATESINPERIOD('Calendar'[date], TODAY(),-7,DAY))

LastWeek = CALCULATE(SUM('Occupational Safety'[Value]),filter(ALL('Occupational Safety'[Week]),'Occupational Safety'[Week]=WEEKNUM(TODAY(),1)-1))

Please assist,

First measure looks correct. Hope the relationship between your tables are fine.

In second table, look like you need to use >= instead of = while doing filter.

LastWeek = CALCULATE(SUM('Occupational Safety'[Value]),filter(ALL('Occupational Safety'[Week]),'Occupational Safety'[Week]>=WEEKNUM(TODAY(),1)-1))

@deevaker  Could you look at my Dax Measure? do all columns have to reference the same table?

LastWeek = CALCULATE(COUNT('SSRS_MissionServices_ActivitesDetail_view'[ActivityID]), 'dimDate'[CalendarYear]),'dimDate'[ISOWeekNumber]=WEEKNUM(TODAY(),1)-1))
