+==========================
+Scrap during manufacturing
+==========================
+
+During the manufacturing process, the need to scrap manufacturing components or finished products
+may arise. This can be necessary if a component or product is damaged, or unusable for any other
+reason.
+
+By default, scrapping a component or finished product removes it from physical inventory and places
+it in a virtual location titled *Virtual Locations/Scrap*. A virtual location is **not** a physical
+space, but rather a designation in Odoo that is used to track items that are no longer in physical
+inventory.
+
+Odoo *Manufacturing* allows for both components and finished products to be scrapped within a
+manufacturing order. The specific type of item that can be scrapped during a manufacturing order
+depends on the stage of the manufacturing process.
+
+.. tip::
+   Scrap orders can be viewed by navigating to :menuselection:`Inventory --> Operations --> Scrap`.
+   Each scrap order shows the date and time the order was created, along with the product and
+   quantity that was scrapped.
+
+   To view the total quantity of each item scrapped, navigate to :menuselection:`Inventory -->
+   Configuration --> Locations`, then remove the :guilabel:`Internal` filter from the
+   :guilabel:`Search...` bar to display all virtual locations. From the list, select the
+   :guilabel:`Virtual Locations/Scrap` location.
+
+Scrap manufacturing components
+==============================
+
+To scrap components during the manufacturing process, begin by navigating to
+:menuselection:`Manufacturing --> Manufacturing Orders`, then select a manufacturing order or click
+:guilabel:`Create` to configure a new one. If a new manufacturing order is created, select a product
+from the :guilabel:`Product` drop-down menu, then click :guilabel:`Confirm`.
+
+Once the manufacturing order has been confirmed, a :guilabel:`Scrap` button appears at the top of
+the page. Click the button and a :guilabel:`Scrap` pop-up window appears.
+

+
+From the :guilabel:`Product` drop-down menu on the :guilabel:`Scrap` pop-up window, select the
+component that is being scrapped, then enter the quantity in the :guilabel:`Quantity` field.
+Finally, click :guilabel:`Done` to scrap the component.
+
+.. image:: scrap_manufacturing/scrap-pop-up.png
+   :align: center
+   :alt: The Scrap pop-up window.
+
+.. important::
+   Before clicking :guilabel:`Mark As Done` on a manufacturing order, only the components of the
+   finished product can be scrapped, **not** the finished product itself. This is because Odoo
+   recognizes that the finished product cannot be scrapped before it has been manufactured.
+
+After scrapping a component, continue the manufacturing process using the required quantity of the
+component that was scrapped. The on-hand stock count for the component that was scrapped updates to
+reflect both the scrapped quantity and the quantity consumed during manufacturing.
+
+.. example::
+   If the manufacturing of a table requires four units of a table leg, and two units of the table
+   leg were scrapped during the manufacturing process, the total quantity of table legs consumed
+   will be six: four units used to manufacture the table plus two units scrapped.
+
+Scrap components from tablet view
+=================================
+
+Components can also be scrapped from the manufacturing tablet view. To do so, select the
+:guilabel:`Work Orders` tab on a manufacturing order, then click the :guilabel:`📱 (tablet view)`
+icon for a work order.
+
+.. image:: scrap_manufacturing/tablet-view-icon.png
+   :align: center
+   :alt: The tablet view icon for a work order.
+
+With tablet view open, click the :guilabel:`☰ (menu)` button at the top left of the screen, then
+select the :guilabel:`Scrap` button on the :guilabel:`Menu` pop-up window. The :guilabel:`Scrap`
+pop-up window then appears.
+
+.. image:: scrap_manufacturing/tablet-scrap-button.png
+   :align: center
+   :alt: The Scrap button on the Menu pop-up window of the manufacturing tablet view.
+
+Finally, select a component from the :guilabel:`Product` drop-down menu and enter the quantity being
+scrapped in the :guilabel:`Quantity` field. Click :guilabel:`Done` to scrap the component.
+
+Scrap finished products
+=======================
+
+Odoo also allows for finished products to be scrapped from a manufacturing order once the order is
+completed. After clicking :guilabel:`Mark as Done`, click the :guilabel:`Scrap` button to make the
+:guilabel:`Scrap` pop-up window appear.
+
+Since the components have been consumed to create the finished product, they will no longer appear
+in the :guilabel:`Product` drop-down menu. Instead, the finished product will be available as an
+option. Select the finished product and enter the quantity to be scrapped in the
+:guilabel:`Quantity` field. Click :guilabel:`Done` to scrap the finished product.
+
+The on-hand stock count for the product that was scrapped will update to reflect both the scrapped
+quantity and the quantity produced during manufacturing.
+
+.. example::
+   If five units of a chair were manufactured, but two units were scrapped after manufacturing was
+   completed, then the on-hand inventory of the chair will increase by three: five units
+   manufactured minus two units scrapped.
