Yearfrac in Query editor does not work?

[Nicolas_viet]

Hey there,

I'm trying to add a custom column showing the days (financial year) between to dates with:

"=yearfrac([StartDate],[EndDate],2)".

When I enter my code in the wizard for custom columns there is no syntax error but after clicking OK it keeps returning an error.

Translated from German it says: "I did not get Yearfrac. Is it written correctly?"

Can anybody help?

Best

Nico

@Nicolas_viet,

If a Power Query solution is needed, try as a Custom Column:

M YEARFRAC ( ) = Duration.TotalDays([EndDate] - [StartDate]) / 360

Basis from your example was '2' - Actual / 360

You might need to figure out the precision however as this was my result:

The Query Editor side of things uses a language called Power Query M, not DAX. As far as I know, YEARFRAC is only available in DAX, so that would be a measure or a calculated column after your data is loaded, rather than a custom column in the Query Editor.
