The *Stock Supply Module* introduces or extends the following concepts:
|
||||
|
||||
.. _model-stock.location:
|
||||
|
||||
Location
|
||||
========
|
||||
|
||||
When the *Stock Supply Module* is activated, the storage location gains new
|
||||
properties that define the default provisioning and overflowing locations for
|
||||
that particular location.
|
||||
|
||||
.. seealso::
|
||||
|
||||
The `Stock Location <stock:model-stock.location>` concept is introduced by
|
||||
the :doc:`Stock Module <stock:index>`.
|
||||
|
||||
.. _model-stock.order_point:
|
||||
|
||||
Order Point
|
||||
===========
|
||||
|
||||
The *Order Point* defines the replenishment policy for a product on a specific
|
||||
location.
|
||||
It established the quantity threshold that determines when stock should be
|
||||
replenished or reduced in order to maintain desired inventory level.
|
||||
|
||||
The desired inventory level is defined as follows:
|
||||
|
||||
* :guilabel:`Minimal Quantity`: the level below which stock must be
|
||||
replenished.
|
||||
|
||||
* :guilabel:`Target Quantity`: the level to which stock should be restored
|
||||
after replenishment.
|
||||
|
||||
* :guilabel:`Maximal Quantity`: the level above which excess stock should be
|
||||
moved.
|
||||
|
||||
There are two types of order point depending on how the replenishment is
|
||||
handled:
|
||||
|
||||
Internal
|
||||
--------
|
||||
|
||||
An *Internal* order point is defined for a storage location, using `internal
|
||||
shipments <model-stock.shipment.internal>` as the replenishment method.
|
||||
When stock falls below the minimum quantity, the system transfers stock from
|
||||
the :guilabel:`Provisioning Location`.
|
||||
When the stock rises above the maximum quantity, the system transfers the
|
||||
excess stock to :guilabel:`Overflowing Location`.
|
||||
|
||||
Purchase
|
||||
--------
|
||||
|
||||
A *Purchase* order point is defined on a `warehouse location
|
||||
<stock:concept-stock.location.warehouse>`.
|
||||
When the stock level falls below the minimum quantity, a `purchase request
|
||||
<purchase_request:model-purchase.request>` is generated to replenish the
|
||||
product from the supplier.
|
||||
|
||||
.. seealso::
|
||||
|
||||
The list of *Order Points* can be found by opening the main menu item:
|
||||
|
||||
|Inventory & Stock --> Order Points|__

|
||||
.. |Inventory & Stock --> Order Points| replace:: :menuselection:`Inventory & Stock --> Order Points`

||||
|
||||
.. _model-purchase.configuration:
|
||||
|
||||
Purchase Configuration
|
||||
======================
|
||||
|
||||
When the *Stock Supply Module* is activated, the purchase configuration gains a
|
||||
new property that defines the replenishment period for stock levels for
|
||||
`purchases <purchase:model-purchase.purchase>`.
|
||||
|
||||
.. seealso::
|
||||
|
||||
The `Purchase Configuration <purchase:model-purchase.configuration>` concept
|
||||
is introduced by the :doc:`Purchase Module <purchase:index>`.

.. _wizard-stock.supply:
|

|
||||
Supply
|
||||
======
|
||||
|
||||
The *Supply* wizard automates product replenishment across `warehouses
|
||||
<stock:concept-stock.location.warehouse>` according to `Order Points
|
||||
<model-stock.order_point>`.
|
||||
It calculates the stock level for each `product
|
||||
<product:model-product.product>` in every warehouses every day over the
|
||||
`supplier period <model-purchase.configuration>` for purchase and over the
|
||||
`lead time <stock:model-stock.location.lead_time>` for internal shipment.

concept of order points.

Order Point
|
||||
***********
|
||||
.. toctree::
|
||||
:maxdepth: 2
|
||||
|
||||
An order point define minimum, maximum and target quantities for a product on a
|
||||
location.
|
||||
|
||||
* The minimum quantity is the threshold quantity below which the provisioning
|
||||
process will be triggered.
|
||||
|
||||
* The maximum quantity is the threshold quantity above which the overflowing
|
||||
process will be triggered.
|
||||
|
||||
* The target quantity is the quantity that will be found in the location after
|
||||
the provisioning / overflowing process has been completed.
|
||||
|
||||
An order point also define a type which can be:
|
||||
|
||||
* Internal
|
||||
|
||||
An Internal order point is defined on a Storage location, it also defines a
|
||||
provisioning and/or an overflowing location. If the minimum quantity is
|
||||
reached it will result in the creation of an internal shipment between the
|
||||
provisioning location and the Storage location. If the maximum quantity is
|
||||
reached it will result in the creation of an internal shipment between the
|
||||
storage location and the overflowing location.
|
||||
|
||||
* Purchase
|
||||
|
||||
A Purchase order point is defined on a warehouse location. If the
|
||||
minimal quantity is reached on the warehouse it will result in a
|
||||
purchase request.
|
||||
|
||||
The internal shipments and purchase requests are created by the supply wizard
|
||||
with respect to stock levels and existing shipments and requests. The
|
||||
stock levels are computed between the next two supply dates computed over the
|
||||
Supply Period from the configuration (default: 1 day). If the stock level of a
|
||||
product without order point on the given warehouse is below zero, a purchase
|
||||
request is also created. The same happens if the stock level of a storage
|
||||
location with a provisioning location is below zero. Likewise, if the stock
|
||||
level of a storage is above zero and an overflow location is defined on the
|
||||
location then an internal shipment will be created.
