Hi,
In Odoo, a Delivery Order is a document that represents the physical movement of goods from a warehouse or inventory location to a customer or another warehouse. It is typically created in response to a Sales Order or a Stock Transfer Order.

When you create a Sales Order in Odoo, you can select a warehouse for each line item. This determines which warehouse the products will be shipped from when the order is fulfilled. Once the Sales Order is confirmed, you can create a Delivery Order for the order.

The Delivery Order includes information about the products being shipped, the quantity of each product, the destination address, and other relevant details. It is used to generate a packing list, shipping label, and other documentation that is required for the shipment.

Hope this will help you
Thanks
