Getting year-to-date for weekly data

[Anonymous]

I have been trying every version of year to date calculations I can find, but I keep just getting the current week in the field. Is the fact that it's weekly rather than monthly the issue? I'm a new Power Bi user, but I cannot find any tutorials anywhere to help.

@Anonymous , you seem to try column, while it should be created as a measure

Try these with Date table . All measures

YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD((Table[Date]),"12/31"))
This Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD((ENDOFYEAR(Table[Date])),"12/31"))

Last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd(Table[Date],-1,Year),"12/31"))
Last YTD complete Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(ENDOFYEAR(dateadd(Table[Date],-1,Year)),"12/31"))

Last to last YTD Sales = CALCULATE(SUM(Sales[Sales Amount]),DATESYTD(dateadd(Table[Date],-2,Year),"12/31"))

Year behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd(Table[Date],-1,Year))
Year + 3 week behind Sales = CALCULATE(SUM(Sales[Sales Amount]),dateadd(dateadd(Table[Date],-1,Year),-21,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 :

var _max = today()
return
calculate(Sum('order'[Qty]),DATESYTD('Date'[Date]),'Date'[Date]<=_max)
//calculate(TOTALYTD(Sum('order'[Qty]),'Date'[Date]),filter('Date','Date'[Date]<=_max))

LYTD QTY forced=
var _max = date(year(today())-1,month(today()),day(today()))
return
CALCULATE(Sum('order'[Qty]),DATESYTD(dateadd('Date'[Date],-1,year)),'Date'[Date]<=_max)
//TOTALYTD(Sum('order'[Qty]),dateadd('Date'[Date],-1,year),'Date'[Date]<=_max)
