Stock Supply Module

The Stock Supply module add automatic supply mechanisms and introduce the concepts of order point and purchase request.

Purchase Request

A purchase request define the need for the purchase of a product. It is linked to a warehouse and eventually a supplier, it contains a ideal purchase date and an expected supply date. A purchase request can be in one of these states:

  • Draft

    A draft purchase request is a request that is not linked to a purchase.

  • Purchased

    A Purchased request is a request that is linked to a purchase which is not in state Done or Cancel.

  • Done

    A purchase request is in state Done if it is linked to a Purchase which is in state Done.

  • Cancel

    A purchase request is in state Cancel if it is linked to a Purchase which is cancelled.

A wizard allow to create purchases based on a selection of Draft purchase requests. The new purchases contains one purchase line by purchase request and group them by warehouse and by supplier. Once the purchases are created, the corresponding purchase requests are set to the state Purchased.

Order Point

An order point define minimum and maximum quantities for a product on a location. The minimum quantity is the quantity that should be always (if possible) available. The maximum is a target quantity that should be reached when re-ordering. An order point also define a type which can be:

  • Internal

    An Internal order point is defined on a Storage location, it also define a provisioning 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.

  • 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 schedulers with respect to stock levels and existing shipments and requests. The stock levels are computed between the next two supply dates. If the stock level of a product without order point on the given warehouse is below zero, a purchase request is also created.
