This section describes the extent and limits of the business process within the supply chain being described in this document. The class diagram of the invoice business transaction is developed in such a way that it specifies the cross industry reusable business information entities. It allows the extension of industry specific business information entities such as product specification details to describe a specific product. It is up to each industry to specify, based on the BRS of the cross industry invoice, its industry specific invoice transaction.
