 Configure products for reordering rules
 =======================================
 
 In order to use reordering rules for a product, it must first be correctly configured. Begin by

-create a new one by clicking :guilabel:`Create`.

-set to :guilabel:`Storable Product`. This is necessary because Odoo only tracks stock quantities for
-storable products, and this number is used to trigger reordering rules.

-automatically generated. By default, the scheduler runs once each day.
+For advanced usage of reordering rules, learn about the following reordering rule fields:

+=======
+
+When stock falls below the reordering rule's minimum, set the reordering rule's *trigger* to

+
+Alternatively, setting the reordering rule's trigger to *manual* displays the product and forecasted
+stock on the *replenishment dashboard*, where the procurement manager can review the stock levels,
+lead times, and forecasted dates of arrival.

-   To manually trigger a reordering rule before the scheduler runs, select :menuselection:`Inventory

+----
+
+Automatic reordering rules, configured by setting the reordering rule's :guilabel:`Trigger` field to
+:guilabel:`Auto`, generates purchase or manufacturing orders when:
+
+#. the scheduler runs, and the *On Hand* quantity is below the minimum
+#. a sales order is confirmed, and lowers the *Forecasted* quantity of the product below the
+   minimum
+
+.. tip::
+   The scheduler is set to run once a day, by default.
+
+   To manually trigger a reordering rule before the scheduler runs, ensure :ref:`developer mode
+   <developer-mode>` is enabled, and select :menuselection:`Inventory app --> Operations --> Run
+   Scheduler`. Then, click the purple :guilabel:`Run Scheduler` button on the pop-up window that
+   appears.
+
+   Be aware that this also triggers any other scheduled actions.
+
+.. example::
+   The product, `Office Lamp`, has an automatic reordering rule set to trigger when the forecasted
+   quantity falls below the :guilabel:`Min Quantity` of `5.00`. Since the current
+   :guilabel:`Forecast` is `55.00`, the reordering rule is **not** triggered.

+Manual
+------
+
+Manual reordering rules, configured by setting the reordering rule's :guilabel:`Trigger` field to
+:guilabel:`Manual`, lists a product on the replenishment dashboard when the forecasted quantity
+falls below a specified minimum. Products on this dashboard are called *needs*, because they are
+needed to fulfill upcoming sales orders, but the forecasted quantity is not enough.
+
+The replenishment dashboard, accessible by navigating to :menuselection:`Inventory app -->
+Operations --> Replenishment`, considers sales order deadlines, forecasted stock levels, and vendor
+lead times. It displays needs **only** when it is time to reorder items.
+
+.. note::
+   If the one-day window for ordering products is too short, skip to the :ref:`visibility days
+   <inventory/product_management/visibility-days>` section to make the need appear on the
+   replenishment dashboard a specified number of days in advance.
+
+When a product appears on the replenishment dashboard, clicking the :guilabel:`Order Once` button
+generates the purchase or manufacturing order with the specified amounts :guilabel:`To Order`.

+Visibility days
+===============
+
+.. important::
+   Ensure :doc:`lead times <../../shipping_receiving/advanced_operations_shipping/scheduled_dates>`
+   are understood before proceeding with this section.
+
+When :ref:`manual reordering rules <inventory/product_management/manual-rr>` are assigned to a
+product, *visibility days* make the product appear on the replenishment dashboard
+(:menuselection:`Inventory app --> Operations --> Replenishment`) a certain number of days in
+advance.
+
+.. example::
+   A product has a manual reordering rule set to trigger when the stock level falls below four
+   units. The current on-hand quantity is ten units.
+
+   The current date is February 20th, and the *delivery date* on a sales order (in the
+   :guilabel:`Other Info` tab) is March 3rd — twelve days from the current date.
+
+   The :ref:`vendor lead time <inventory/management/purchase-lt>` is four days, and the
+   :ref:`purchase security lead time <inventory/management/purchase-security-lt>` is one day.
+
+   When the :guilabel:`Visibility Days` field of the reordering rule is set to zero, the product
+   appears on the replenishment dashboard five days before the delivery date, which, in this case,
+   is February 27th.
+
+   .. image:: reordering_rules/need-dates.png
+      :align: center
+      :alt: Graphic representing when the need appears on the replenishment dashboard: Feb 27th.
+
+   To see the product on the replenishment dashboard for the current date, February 20, set
+   the :guilabel:`Visibility Days` to `7.00`.
+
+To determine the amount of visibility days needed to see a product on the replenishment dashboard,
+subtract *today's date* from the *date the need appears* on the replenishment dashboard.
+
+.. math::
+
+   Visibility~days = Need~appears~date - Today's~date
+
+.. example::
+   Referring to the example above, today's date is February 20th, and the need for the product
+   appears on February 27th.
+
+   (February 27 - February 20 = 7 days)
+
+   Incorrectly setting the :guilabel:`Visibility Days` fewer than seven days in this case results in
+   the need **not** appearing on the replenishment dashboard.

+Route
+=====
 
 Odoo allows for multiple routes to be selected under the :guilabel:`Inventory` tab on each product
 form. For instance, it is possible to select both :guilabel:`Buy` and :guilabel:`Manufacture`, thus
 enabling the functionality of both routes.
 
 Odoo also enables users to set a preferred route for a product's reordering rule. This is the route
-that the rule defaults to if multiple are selected. To select a preferred route, begin by navigating
