Hi,
I was trying to calculate for the qty between dates from the last 4 weeks (28 days) to a selected date.
I tried using the dateadd function to specify the range but it didnt work..
this is what I have so far
Qty last 4 weeks = calculate(sum(data[qty], datesbetween(data[date], dateadd(data[date], -28, days]), dateadd(data[date], 0, days])
To get the aggregated qty for the past 4 weeks (monday through saturday) from the date selected on my filter.
seems I cant use the dateadd function to call out a sepecific for datesbetween.
Please can anyone help? Thank you very much.

@yve214 , if you need rolling 28 days
Rolling 28 = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date ],MAX('Date'[Date ]),-28,DAY))
if you need 4 weeks, You need the following columns in your date table
new columns
Week Start date = 'Date'[Date]+-1*WEEKDAY('Date'[Date],2)+1
Week End date = 'Date'[Date]+ 7-1*WEEKDAY('Date'[Date],2)
Week Rank = RANKX(all('Date'),'Date'[Week Start date],,ASC,Dense)
OR
Week Rank = RANKX(all('Date'),'Date'[Year Week],,ASC,Dense) //YYYYWW format
measure
Last 4 weeks = CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=max('Date'[Week Rank])-4 && 'Date'[Week Rank]<=max('Date'[Week Rank])))
or
Last 4 weeks =
var _max1 = maxx(allselected('Table'), 'Table'[date])
var _max = maxx(filter(all(date), date[date] = _max1), week[Rank])
return
CALCULATE(sum('Table'[Qty]), FILTER(ALL('Date'),'Date'[Week Rank]>=_max-4 && 'Date'[Week Rank]<=_max))
