21.3.2 Assembly Bills of Materials

Note: Sales Bills of Materials In some software this is named a Sales Bill of Materials. In Open ERP the term assembly is used because the effect of the bill of materials is visible not only in sales but also elsewhere, for example in the intermediate manufactured products. Assembly bills of materials enable you to define assemblies that will be sold directly. These could also be used in deliveries and stock management rather than just sold in isolation. For example if you deliver the cabinet in pieces for self-assembly, set the ARM100 BoM to type Assembly . When a salesperson creates an order for an ARM100 product, Open ERP automatically changes the ARM100 from a set of components into an identifiable package for sending to a customer. Then it asks the storesperson to pack 2 PANLAT, 1 PANA100, 4 PROFIL, 3 ETA100. This is described as an ARM100 not just the individual delivered products. Example: Large distributor As an example of using these assemblies, take the case of a supermarket. In a supermarket, you can buy bottles of cola individually or in a pack of 6 bottles. The pack and the bottles are two different products and the barcodes used are also different. But customers have the right to open a pack and extract some bottles to take them individually to the checkout. The supermarket can not track its stock in packs and bottles any more, but only individually in bottles. So you can define a bill of materials for sale which defines a pack as an assembly of 6 bottles. Then when you have sold a pack, you can find a pack on the invoice or bill of sale but the associated stock operation will still be 6 bottles. In the case of this assembly, this is not a production order to transform the product. The transformation is done directly between the order and the set. Note: Assemblies and Purchases The use of assemblies for selling to customers has been described here, but this functionality works just as well for purchases from suppliers. So in the example of a supermarket, you can buy cola in packs and the storesperson will see a number of bottles at goods in reception.

21.3.3 Configurable Bills of Materials

In Open ERP you can define several bills of materials for the same product. In fact you can have several manufacturing methods or several approved raw materials for a given product. You will see in the following 300 section that the manufacturing procedure the routing is attached to the Bill of Materials, so the choice of bill of materials implicitly includes the operations to make it. Once several bills of materials have been defined for a particular product you need to have a system to enable Open ERP to select one of them for use. By default the bill of materials with the lowest sequence number is selected by the system. To gain more control over the process during the sale or procurement, you can use properties. The menu Manufacturing → Configuration → Master Bill of Materials → Properties enables you to define properties, which can be defined arbitrarily to help you select a bill of materials when you have a choice of BoMs. Note: Properties Properties is a concept that enables the selection of a method for manufacturing a product. Properties define a common language between salespeople and technical people, letting the salespeople to have an influence on the manufacture of the products using non-technical language and the choices decided on by the technicians who define Bills of Materials.
