+Partial reservation
+-------------------
+
+After :ref:`completing the packaging setup <inventory/management/packaging-setup>`, packagings can
+be reserved in full or partial quantities for outgoing shipments. Partial packaging flexibility
+expedites order fulfillment by allowing the immediate shipment of available items, while awaiting
+the rest.
+
+To configure packaging reservation methods, go to :menuselection:`Inventory app --> Configuration
+--> Product Categories`. Then, click :guilabel:`Create`, or select the desired product category.
+
+On the product category's form, in the :guilabel:`Logistics` section, :guilabel:`Reserve Packagings`
+can be set to :guilabel:`Reserve Only Full Packagings` or :guilabel:`Reserve Partial Packagings`.
+
+.. important::
+   To see the :guilabel:`Reserve Packaging` field, the :guilabel:`Product Packaging` feature
+   **must** be enabled. To enable this feature, go to :menuselection:`Inventory app -->
+   Configuration --> Settings`, scroll to the :guilabel:`Products` section, tick the
+   :guilabel:`Product Packagings` checkbox, and click :guilabel:`Save`.
