Weeknum function error - can't get ISO week

‎06-20-2023 12:03 AM

From all the documentation I have seen, this DAX code should give me the ISO week number for today:

Week = WEEKNUM(Today(), 21)

But this is giving me an error, saying 21 is not the correct parameter type. When it gives me the available options, only 1 and 2 appear:

MAG_PRG_0-1687243876954.png


The documentation here seems to clearly state that 21 is a valid option for return_type:
https://learn.microsoft.com/en-us/dax/weeknum-function-dax

Does anyone know why it will not accept 21 as the parameter?
