What is a push rule?
|
|
====================
|
|
|
|
Overview
|
|
=========
|
|
|
|
The push system of inventory control involves forecasting inventory
|
|
needs to meet customer demand. Companies must predict which products
|
|
customers will purchase along with determining what quantity of goods
|
|
will be purchased. The company will in turn produce enough product to
|
|
meet the forecast demand and sell, or push, the goods to the consumer.
|
|
Disadvantages of the push inventory control system are that forecasts
|
|
are often inaccurate as sales can be unpredictable and vary from one
|
|
year to the next. Another problem with push inventory control systems is
|
|
that if too much product is left in inventory, this increases the
|
|
company's costs for storing these goods. An advantage to the push system
|
|
is that the company is fairly assured it will have enough product on
|
|
hand to complete customer orders, preventing the inability to meet
|
|
customer demand for the product.
|
|
|
|
A push flow indicates how locations are chained with the other ones. As
|
|
soon as a given quantity of products is moved in the source location, a
|
|
chained move is automatically foreseen according to the parameters set
|
|
on the flow specification (destination location, delay, type of move,
|
|
journal). It can be triggered automatically or manually.
|
|
|
|
Configuration
|
|
=============
|
|
|
|
Push rules are part of the routes. Go to the menu
|
|
:menuselection:`Inventory --> Configuration --> Settings`
|
|
and tick **Advance routing of products using rules**.

Push rules settings
|
|
===================
|
|
|
|
The push rules are set on the routes.
|
|
Go to :menuselection:`Configuration --> Routes`.
|
|
|
|
In the push rule section, click on **Add an item**.
|
|

|
:align: center
|
|
|
|
Here you can set the conditions of your rule. In this example, when a
|
|
good is in **Input location**, it needs to be moved to the quality control.
|
|
In the 3 steps receipts, another push rule will make the goods that are
|
|
in the quality control location move to the stock.

Try to create a push rule in our demo instance.
|
|
|
|
.. note::
|
|
Some warehouse configuration creates routes with push rules
|
|
already defined.
|
|
|
|
Stock transfers
|
|
===============
|
|
|
|
The push rule will trigger stock transfer. According to the rule set on
|
|
your route, you will see that some transfers might be ready and other
|
|
are waiting.
|
|
|
|
The push rule that was set above will create moves from **WH/Input**
|
|
location to the **WH/Quality Control** location.
|
|

|
In this example, another move is waiting according to the second push
|
|
rule, it defines that when the quality control is done, the goods will
|
|
be moved to the main stock.
