Understanding Pull/Push rules in supply routes¶

In inventory management, the supply chain is a very important process to provide goods to whoever needs them quickly and on time. If you have a big warehouse with thousands of products, supply chain management becomes even more difficult than ever. Viindoo software assists you in setting up such an automatic supply chain, making warehouse management easier.

Operating principles¶

Pull rule¶

When there is a demand for goods at a location, the software will look for a pull rule set up on this location and create a stock transfer from the location they are found to this point of need.

For example: When the customer places an order, a demand will arise at the Customer Location. The software will then look for the pull rule set up on this location. Suppose, if Stock Location 1 is set up according to the rule to deliver goods to the Customer Location when there is a need, the system will generate a stock transfer from Stock Location 1 to Customer Location. But if the goods are out of stock at the Stock Location 1, the software will use the rules set up on the Stock Location 1 to supply them until your customer receives the goods.

Push rule¶

A push rule is triggered when goods are received at a specific source location. Viindoo software will create a transfer to deliver the product to the destination location.

Example: Let’s look at products that are set up with the three-steps routes. Once the goods have arrived at the Input location, they will be moved to the Quality Control location. After the inspection is complete, the products are automatically taken to the Stock location for storage.

Routes¶

A replenishment route is a path of goods built by using either the Pull, the Push, or a combination of both. Viindoo software will generate a stock transfer to rotate the goods from one location to another (from a source location to a destination).

Example: When there is demand at a customer location, product A is pulled from the main stock location. If product A is out of stock or the quantity is not enough at the main location, it will be pulled from the vendor location. Hence, the route of product A is Vendor location > Stock location > Customer Location using the Pull rule.

How to use Routes and Pull/Push rule¶

Name: The name of this rule. In this example is WH: Stock → Customers.
Action: Each company has its own business operation and will therefore use different actions to meet their needs: Pull, Push, Pull & Push, Buy or Manufacture. Each actions has a specific instruction next to it for users to understand the product’s flow. For each action, there is a corresponding supply method. For example: If you select Pull From, the corresponding supply methods are:
- Take From Stock: When a product is needed, the system will check the stock on hand and pull the product from this location if the quantity is enough for delivery. Else the supply route will terminate.
- Trigger Another Rule: The system will not check the stock on hand and trigger another rule instead for supply.
- Take From Stock, If unavailable, Trigger Another Rule: First, operate the Take From Stock method, if the quantity is not enough, switch to Trigger Another Rule rule.
If you select Buy, a request for quotation is created when a product is needed when product is on-demand.
Operation Type: There are 3 main types: Receipts, Delivery Orders, Internal Transfers. If you install Manufacturing, you will see one more operation type called Manufacture.
Source Location: The location that delivery the goods.
