I'm just starting wiht PowerBI desktop.
My request :
-I have an excel file including a Date
-I load it in PBI GOOD.
-I want to create a field 'month date'
I'm triing infor shared on https://community.powerbi.com/t5/Desktop/Transform-date-to-MM-YYYY/m-p/205311#M90409
but it failed each time : FORMAT function unknown.
additionnal info : my power BI is in French, I cannot find a way to change to english. could be the issue.
Go to Solution.
One more thing you should be noticed that, when you use FORMAT() function to transform the date. It will be a text type value not a date any more.
So if you still want to keep it as date. You can try the build in "MMMM yyyy" date format. Choose your date column, go to Modeling and you can find this date format at Format option.

The link you shared is for PowerQuery not PowerBI.
Dax should be: =FORMAT(DateColumn;"YYYY-MM")
