I just upgraded to Odoo 19 and after testing out some of the different functions in Odoo 19, the Valuation Section disappear - It was there.

I did re-install ( and then upgrade) the inventory the purchase module.

My products are save as Goods not service.

Navigate to the Inventory app.

Go to Configuration > Settings.

Scroll to the Valuation section

I am also having another issue. after creating a purchase order, it does not allow me to receive it
