Tryton application platform - production outsourcing module

 Tryton is a high-level general purpose application platform. It is the base
 of a complete business solution as well as a comprehensive health and hospital
 information system (GNUHealth).
 .
 The production outsourcing module allows to outsource production order per
 routing. When such outsourced production is set to waiting, a purchase order is
 created and its cost is added to the production.
 .
 To define an outsourced production, the routing must have a *Supplier*, a
 *Service* and its *Quantity* defined. Those values will be used to create the
 purchase order. The bought quantity is computed by multiplying the *Quantity*
 by the factor between the bill of material and the production quantity.
