Hello there @NewbieJono ! Imagining you are adding up the values for a column the Dax would be as follows:

 

Total_value =
CALCULATE(
SUM(Table[Column]),
DATEADD(Date_Table[Date_Column], -7, DAY)
)

 

Hope this answer solves your problem!

Try this ...

Variance % =

VAR salesthisweek =
SUM(Query[Sale])

VAR salespreviousweek =
CALCULATE(SUM(Query[Sale]),
DATEADD(Query[Date],-7,DAY)
)

RETURN
DIVIDE(salespreviousweek , salesthisweek)

You can add Relative Week column into your date table and calculate total snapshot for last week and current week then the difference between both weeks. 

 

For Relative Week add following columns to date table:  

StartOfWeek = DimDate[Date] - WEEKDAY(DimDate[Date],2) + 1

StartOfCurrentWeek = TODAY() - WEEKDAY(TODAY(),2) + 1

RelativeWeek = (DimDate[StartOfWeek] - DimDate[StartOfCurrentWeek])/7

 

Now can create a measure to calculate weekly difference: 

 

WoW DIff = 

WoW diff =
VAR past_week =
    CALCULATE( [Total Cost], 'Date'[Relative Week] = -1 )
VAR cur_week =
    CALCULATE( [Total Cost], 'Date'[Relative Week] = 0 )
RETURN
    cur_week - past_week

this is working thank you, how could i expand this to show % change ?

Hello there @NewbieJono ! You can do it like so:

 % Change =

var _current = SUM(Table[Column])

var _previous =
CALCULATE( SUM( Table[Column] ),
DATEADD( Date_Table[Date_column], -7, DAY)
)

var _diff = _current - _previous

RETURN
DIVIDE(_diff, _previous) 

And then format the value as a "%" in the "Format" ribbon!

Hope this answer solves your problem!
