The only product we have entered into Odoo so far is the medium white T-shirt, which is blank. Nothing is printed on the T-shirt when it is received from the supplier. Now, we want to create a manufacturing order that will produce a new product in which we print on the T-shirt a design of the customer's choice.

For our operations, we can still use the medium white T-shirt. But now, instead of selling the blank T-shirt directly to our customer, it will be used as a raw material for our manufacturing order.

Let's first configure the final product that is to be created during the manufacturing process, that is, the complete T-shirt with the final design that will ship to the customer. For our example, it will be a Class of 2017 T-shirt.

Odoo allows you the ability in most forms, where it is appropriate, to create a product on the-fly. Let's create a product by clicking the drop-down arrow in the Product tab, and choosing Create and Edit...: 

Using the quick Create and Edit..., you can add your finished products directly when creating a manufacturing order. In some workflows, where you may use a separate system for handling sales orders, this option can be a fast way to create the required finished products to push into the inventory.

Next, you will fill out the product form with the fields required for a finished product:

The General Information and Inventory tabs should look familiar by now. Starting in Odoo 9, Odoo provided routes that allowed a lot of flexibility in defining complex workflows and supply management operations. Fortunately, the more common routes are already configured, and we can check Manufacture to let Odoo manufacturing know that this product is part of the manufacturing workflow. Only products that have the supply method of Manufacture can be selected as a product on a manufacture order.

Please also notice at the top of the form that the Can be Purchased box is unchecked. This will keep this product from appearing in the product list on a purchase order. Since we cannot purchase this product directly from a supplier, we don't want it appearing in our product list when working within purchasing.
