Splitting Date information into weeks
Hello, I'm having an issue with splitting date time into weeks. I'm unsure of how to accomplish this given the fact that I am using a live dataset connection. I guess the underlying question is h...

For the live-connection mode, you can add the weeknum using the measure below:
Measure 2 = WEEKNUM(MAX(Table1[Date]),2)
Hi,
Could you add the calculation in your query, M language Date.WeekOfYear() instead of using DAX WEEKNUM() ?
In case you need ISO Weeknum, you can use this M code :
//Calculation of ISO Weeknumber in 4 steps
//1. Calculate the Thursday of the week
InsertCurrThursday = Table.AddColumn(InsertMonthEnding, "CurrThursday", each Date.AddDays([DateRef], -Date.DayOfWeek([DateRef],1) + 3), type date),
//2. Calculate 1st of january (cf step 1)
InsertFirstJan = Table.AddColumn(InsertCurrThursday, "FirstJan", each
#date(Date.Year([CurrThursday]),1,1),type date),
//3. Calculate number of days between 1st january and thursday
InsertDuration= Table.AddColumn(InsertFirstJan, "Duration", each Duration.Days(Duration.From([CurrThursday] - [FirstJan])), type number),
//4. Divide the calculated number of days at step 3 by 7, round down and add 1
InsertISOWeekNum = Table.AddColumn(InsertDuration, "NumWeekISO", each Number.RoundDown([Duration]/7)+1), ChangeType5=Table.TransformColumnTypes(InsertISOWeekNum,{{"NumSemISO", Int64.Type}}),
//Remove unusefull columns
RemovedColumns = Table.RemoveColumns(ChangeType5, {"CurrThursday","FirstJan","Duration"})Hope this help,

Unfortunately I dont have any powerquery/ query editing ability. I appreciate the help though!
I also should mention that I have no ability to manipulate the data at the database level. I can only use the functionality limited to live dataset connections.
