Distinct number of orders per year

[Mederic]

Hello everyone,

I have a data table in which I would like to count the number of distinct orders.
I have integrated my source into Power Pivot and selected the option "Distinct Count"

But it doesn't work. I would like to have the result in the table in green (see picture)
Do I need to go through a measure and if so which one?

Thank you in advance for your help

Regards

you need to create a mearsure

=DISTINCTCOUNT(Table[PO])
