+Scrap inventory
+===============
+
+In some cases, a product in inventory may be damaged or found to be defective. If it is not possible
+to repair or return the product, Odoo *Inventory* allows users to scrap it, ensuring that usable
+inventory counts remain accurate.
+
+.. 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`. Remove the :guilabel:`Internal` filter from the
+   :guilabel:`Search...` bar to display virtual locations. Finally, select the :guilabel:`Virtual
+   Locations/Scrap` location.
+
+By default, scrapping a 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.
+
+.. admonition:: Learn more
+
+   For more information about virtual locations, see the documentation about the different types of
+   :ref:`locations <inventory/management/difference-warehouse-location>`.
+
+Scrap from stock
+================
+
+To scrap a product located in inventory, begin by navigating to :menuselection:`Inventory -->
+Operations --> Scrap`. On the :guilabel:`Scrap Orders` page, click :guilabel:`Create` to configure a
+new scrap order.
+
+On the scrap order, select the product being scrapped from the :guilabel:`Product` drop-down menu,
+then enter the quantity in the :guilabel:`Quantity` field. The :guilabel:`Source Location` defaults
+to the location where the product is stored, and the :guilabel:`Scrap Location` defaults to
+:guilabel:`Virtual Locations/Scrap`, but either of these can be changed by selecting a different
+location from their respective drop-down menus.

+
+Finally, click :guilabel:`Validate` to scrap the product. The on-hand inventory count for the
+scrapped product updates to subtract the scrapped quantity.
+
+Scrap from a receipt, transfer, or delivery
+===========================================
+
+It is also possible to scrap products during the receipt, transfer, and delivery operations. This
+can be necessary if any products are found to be defective when receiving them into inventory,
+transferring them from one location to another, or preparing them for delivery.
+
+To scrap a product during the receipt, transfer, or delivery operations, begin by navigating to the
+:menuselection:`Inventory` app. On the :guilabel:`Overview` page, select the :guilabel:`# TO
+PROCESS` button on the :guilabel:`Receipts`, :guilabel:`Internal Transfers`, or :guilabel:`Delivery
+Orders` card, depending on the type of operation the product is being scrapped from.
+
+.. note::
+   For the :guilabel:`Internal Transfers` card to appear on the :menuselection:`Overview` page of
+   the :menuselection:`Inventory` app, the :guilabel:`Storage Locations` setting must be enabled. To
+   do so, navigate to :menuselection:`Configuration --> Settings`, then enable the checkbox next to
+   :guilabel:`Storage Locations` under the :guilabel:`Warehouse` heading.
+
+Alternatively, a list of all delivery orders, receipts, and transfers can be viewed by navigating to
+:menuselection:`Inventory --> Operations --> Transfers`.
+
+Next, open a delivery order, receipt, or transfer from the corresponding page by clicking on it. A
+:guilabel:`Scrap` button appears at the top of the page. Click it to open the :guilabel:`Scrap`
+pop-up window.
+
+.. image:: scrap_inventory/scrap-pop-up.png

+
+.. important::
+   The :guilabel:`Scrap` button will only appear on a receipt that has been validated. This is
+   because Odoo only allows products to be scrapped once they have been entered into inventory.
+
+On the :guilabel:`Scrap` pop-up window, select the product being scrapped from the
+:guilabel:`Product` drop-down menu. Then, enter the quantity in the :guilabel:`Quantity` field.
+
+The :guilabel:`Source Location` defaults to the location where the product is stored, and the
+:guilabel:`Scrap Location` defaults to :guilabel:`Virtual Locations/Scrap`, but either of these can
+be changed by selecting a different location from their respective drop-down menus.
+
+Finally, click :guilabel:`Done` to scrap the product. After doing so, the :guilabel:`Scrap` pop-up
+window disappears and a :guilabel:`Scraps` smart button appears in the top right of the page. Click
+it to view all of the scrap orders created from that operation.
