    Try this instead

    Year-Mon = FORMAT('Table'[Date], "YYYY-MM")

    Good Luck! :smileyhappy:

    RvdHeijdenHere's DAX

     

    Year-Wk = 
    YEAR ( 'Calendar'[Date] ) & "-"
        & CONCATENATE (
            IF ( WEEKNUM ( 'Calendar'[Date] ) < 10, "0", "" ),
            WEEKNUM ( 'Calendar'[Date] )
        )

     

    Yes you may have to adjust WEEKNUM depending on when your week starts SUN (1) on MON (2)

    I have skipped this optional parameter because the default is 1 which is what i need.

     

    Hope this helps.

    Good Luck!:smileyhappy:

    Sorry, but I'm afraid not. Probably the DAX week number does NOT return the ISO Week number (unless I'm terribly mistaking as I'm not a DAX expert).

      It seems that you can supply 21 as second parameter to the WEEKNUM Function to obtain the ISO Week Number, see comments below Microsofts documenetation.
