is there a nextweek function or similar in dax?

[Anonymous]

I have a full DimDate dimension with all columns, and I try to filter data for ‘next week’.

I have tried:

'Date'[Week Year Week Number] = CONVERT(CONCATENATE( YEAR(TODAY()  ),WEEKNUM(TODAY(),21)    ),INTEGER)+1    

But of course I have 2 problems:

•  when week is 52, I will just get 53.
• Also the column  Week Year Week Number   has values like 202202 And my WEEKNUM concat returns something like 20222 (they are different!)

How can I appropriately filter for ‘next week’ data?

@Anonymous  you can always create a custom Calendar table with continuous WEEKNUM to help you in next week filtering

Calendar=
VAR _cal1 =
    CALENDAR ( DATE ( 2010, 1, 1 ), DATE ( 2020, 1, 1 ) )
VAR _cal2 =
    ADDCOLUMNS (
        _cal1,
        "weekNum",
            VAR _minDate =  --- what is the min date in this calendar table
                MINX ( _cal1, [Date] )
            VAR _x =
                WEEKDAY ( _minDate, 1 ) - 1
            VAR _y = _minDate - _x
            VAR _z =
                CEILING ( DIVIDE ( ( [Date] - _y ), 7 ), 1 ) ---[Date] - _y gives the last Sunday before the minDate in the calendar
            RETURN                                           ---from when the WEEKNUM starts
                _z
    )
RETURN
    _cal2

I had a similar issue to yours, but instead of next week, my desire was the previous month. I needed to get month 12 when it was month 1, not month 0.

I'm still a novice, but I achieved mine with an IF() statement.

Try something like this. The FORMAT() pads the number with a leading zero up to two digits. This also accounts for the year being different when it's the last week of the year.

VAR varNextWeekNum = FORMAT(IF(WEEKNUM(NOW(),21)=52,1,WEEKNUM(NOW(),21)+1),"00")
VAR varNextWeekYear = IF(WEEKNUM(NOW(),21)=52,YEAR(NOW())+1,YEAR(NOW()))
RETURN
CONVERT(CONCATENATE(varNextWeekYear,varNextWeekNum),INTEGER)

EDIT: Fixed code mistake.

There are no built in functions for time intelligence at the week level.

I would start by having a look at: Week-Based Time Intelligence in DAX - SQLBI
