    Hey Anonymous ,

     

    you can use this DAX statement instead:

    Reports_Lst2Wks_ALT = 
var _today = TODAY()
var _7DaysBeforeToday = _today -7
return
CALCULATE(
DISTINCTCOUNT(selfreports[AccountName])
,DATESBETWEEN(selfreports[Date] , _7DaysBeforeToday , _today)
)

    DATESINPERIOD requires a dedicated date table without gaps, for this I recommend following the link Greg_Deckler provided in his post.

     

    Hopefully, this helps to tackle your challenge.

     

    Regards,

    Tom

or measures like, with date calendar

Rolling 14day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX(Sales[Sales Date]),-14,Day))

Rolling 14day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],MAX('Date'[Date]),-14,Day))

Rolling 14day = CALCULATE(sum(Sales[Sales Amount]),DATESINPERIOD('Date'[Date],Today(),-14,Day))

 

To get the best of the time intelligence function. Make sure you have a date calendar and it has been marked as the date in model view. Also, join it with the date column of your fact/s. Refer :
