Qu’est-ce qu’une stratégie de sortie (FIFO, LIFO et FEFO)?

Vue d’ensemble

Removal strategies are usually in picking operations to select the best products in order to optimize the distance for the worker, for quality control purpose or due to reason of product expiration.

When a product movement needs to be done, Odoo will find available products that can be assigned to shipping. The way Odoo assign these products depend on the removal strategy that is defined on the product category or on the location.

Configuration

Dans l’application Inventaire, allez à Configuration ‣ Paramètres :

../../../../../_images/removal01.png ../../../../../_images/removal02.png

Check Track lots or serial numbers, Manage several location per warehouse and Advanced routing of products using rules, then click on Apply.

Then, open Configuration ‣ Locations and open the location on which you want to apply a removal strategy.

Types de stratégie de retrait

FIFO ( First In First Out )

Une stratégie First In First Out implique que les produits entrées en premier dans le stock, sortiront en premier. Les entreprises qui vendent des produits périssables doivent utiliser la méthode FIFO. Les entreprises vendant des articles dont le cycle de demande est relativement court, comme des vêtements, peuvent également devoir choisir la méthode FIFO pour s’assurer qu’elles ne sont pas coincées avec des styles périmés en stock.

Allez à Stock ‣ Configuration ‣ Sites, ouvrez l’emplacement du stock et configurez la stratégie de sortie FIFO.

Prenons un exemple de stratégie de sortie FIFO

In your warehouse stock (WH/Stock) location, there are 3 lots of iPod 32 Gb available.

Vous pouvez trouver des détails sur l’inventaire disponible dans le rapport de valorisation de l’inventaire.

../../../../../_images/removal04.png

Créez un bon de commande de 25 unités de iPod 32 GB et confirmez le.

Vous pouvez voir dans le produit de l’envoi sortant que l’article Ipod 32 Gb est assigné avec les lots le plus anciens, en utilisant la stratégie de sortie FIFO.

LIFO (Last In First Out)

In this warehouse management, the products which are brought in the last, moves out the first. LIFO is used in case of products which do not have a shelf life.

Allez à Inventaire ‣ Configuration ‣ Emplacements, ouvrez l’emplacement du stock et configurez la stratégie de sortie LIFO.

In our example, let’s check the current available stock of Ipod 32 Gb on WH/Stock location.

../../../../../_images/removal06.png

Create a sale order with 10 units of Ipod 32 Gb.

You can see in the outgoing shipment product that the Ipod 32 Gb are assigned with the newest lots, using the LIFO removal strategy.

FEFO ( First Expiry First Out )

In FEFO warehouse management, the products are dispatched from the warehouse according to their expiration date.

Allez à Inventaire ‣ Configuration ‣ Paramètres. Cochez l’option Définir la date d’expiration des numéros en série. Cliquez ensuite sur Appliquer pour enregistrer les modifications.

This will allow you to set four expiration fields for each lot or serial number: best before date, end of life date, alert date and removal date. These dates can be set from Inventory Control ‣ Serial Numbers/Lots.

../../../../../_images/removal09.png
  • Best Before Date: This is the date on which the goods with this serial/lot number start deteriorating, without being dangerous yet.

  • End of Life Date: This is the date on which the goods with this serial/lot number may become dangerous and must not be consumed.

  • Removal Date: This is the date on which the goods with this serial/lot number should be removed from the stock. Using the FEFO removal strategy goods are picked for delivery orders using this date.

  • Alert Date: This is the date on which an alert should be sent about the goods with this serial/lot number.

Lots will be picked based on their removal date, from earliest to latest. Lots without a removal date defined will be picked after lots with removal dates.

All dates except removal date are for informational and reporting purposes only. Lots that are past any or all of the above expiration dates may still be picked for delivery orders, and no alerts will be sent when lots pass their alert date.

Expiration dates on lots can also be set automatically when goods are received into stock. After enabling expiration dates on serial numbers, four new fields will become available in the inventory tab of the product form: product life time, product use time, product removal time, and product alert time. When an integer is entered into one of these fields, the expiration date of a lot/serial of the product in question will be set to the creation date of the lot/serial number plus the number of days entered in the time increment field. If the time increment field is set to zero, then the expiration date of a lot/serial must be defined manually after the lot has been created.

Each of these time increment fields is used to generate one of the lot expiration date fields as follows:

Product Use Time –> Best Before Date

Délai avant retrait –> Date de retrait

Durée de vie du produit –> Fin de la date limite

Product Alert Time –> Alert Date

To set the removal strategy on location, go to Configuration ‣ Locations and choose FEFO.

Let’s take an example, there are 3 lots of ice cream available in WH/Stock location: LOT0001, LOT0002, LOT0003 with different expiration date.

Lot / Numéro de série

Produit

Date d’expiration

LOT0001

Crème glacée

20/08/2015

LOT0002

Crème glacée

10/08/2015

LOT0003

Crème glacée

15/08/2015

We will create a sale order with 15kg of ice cream and confirm it.

The outgoing shipment related to sale order will make the move based on removal strategy FEFO.

It will take 10kg from LOT0002 and 5kg from LOT0003 based on the removal dates.
