Hi All,
In D365, I am trying to setup calendar so that system throws error when user selects Delivery date as a weekend or holiday. But unable to achieve this, can anyone help?
I have set my Production calendar, where 10/20 is supposed be holiday. When I am creating a PO and selecting 10/20 as delivery date my expectation is system should throw error and not allow me to select this date as it's a holiday. But it's not throwing any error.

I have also marked the "Deafult order setting" for the items to be only "working days" and also updated the vendor Purchase calendar
