The Product Order ABE contains all entities required to specify a communication used to procure or update one or many Products in the context of a ProductOffering. This pattern is used to define: • CustomerProductOrder corresponding to Products ordered by a Customer to the Service Provider • and BusinessPartnerProductOrder corresponding to Products ordered by the Service Provider to a Business Partner Note: Some but not all enterprises consider an Order to be a type of an Agreement. From a SID model perspective, an Order can be formalized by an Agreement and the Agreements relationship between the Agreement and the ProductOrder. This philosophy has the advantage of clearly separating two different concepts: the order from the legal formalisms associated with the order. For example, several orders may refer to the same Agreement.<br/>
