Procurements & Procurement Rules ================================ A procurement is a request for a specific quantity of products to a specific location. They can be created manually or automatically triggered by: .. rst-class:: alternatives doc-aside New sale orders Effect A procurement is created at the customer location for every product ordered by the customer (you have to deliver the customer) Configuration Procurement Location: on the customer, field "Customer Location" (property) Minimum Stock Rules Effect A procurement is created at the rule's location. Configuration Procurement location: on the rule, field "Location" Procurement rules Effect A new procurement is created on the rule's source location *Procurement rules* describe how procurements on specific locations should be fulfilled e.g.: * where the product should come from (source location) * whether the procurement is :abbr:`MTO (Made To Order)` or :abbr:`MTS (Made To Stock)` .. h:div:: doc-aside .. todo:: needs schema thing from FP Routes ====== Procurement rules are grouped in routes. Routes define paths the product must follow. Routes may be applicable or not, depending on the products, sales order lines, warehouse,... To fulfill a procurement, the system will search for rules belonging to routes that are defined in (by order of priority): .. rst-class:: alternatives doc-aside Warehouses Warehouse Route Example: Pick → Pack → Ship Picking List: Pick Zone → Pack Zone Pack List: Pack Zone → Gate A Delivery Order: Gate A → Customer Routes that describe how you organize your warehouse should be defined on the warehouse.

They automatically move the product to a new location. Whether a push rule can be used depends on applicable routes. .. rst-class:: alternatives doc-aside Quality Control * Product lands in Input * Push 1: Input → Quality Control * Push 2: Quality Control → Stock Warehouse Transit * Product lands in Transit * Push: Transit → Warehouse 2 Procurement Groups ================== Routes and rules define inventory moves. For every rule, a document type is provided: * Picking * Packing * Delivery Order * Purchase Order * ... Moves are grouped within the same document type if their procurement group and locations are the same. A sale order creates a procurement group so that pickings and delivery orders of the same order are grouped. But you can define specific groups on reordering rules too. (e.g. to group purchases of specific products together)
