Power BI DATEADD function returns blank for future dates

Question

In Power BI, I have a simple calendar created with the formula CALENDAR = CALENDAR( DATE(2014,12,1), TODAY()).
I added another column, that would contain dates 1 month later then the original Date column, with the formula ADVANCED_DATES = DATEADD('CALENDAR'[Date], 1, MONTH).

I noticed that dates going into the future are left blank (today is 01/December/2023). Do you know what is causing it and how can I fix it?

(I have dates in the original Date column I am using, as you can see on the screenshot)

Answer 1

DATEADD(...) is a Time Intelligence function, and as per the documentation:

The result table includes only dates that exist in the dates column.

So you will need to extend your CALENDAR to have the future dates needed.

Alternatively, if this is only for a Calculated Column then you can use this expression:

Date +1 Month = EDATE([Date], 1)
