The system watches for an invoice to be added to the Invoices repository. You can use the optional parameters within this element to further define the type of invoice to watch for.
Technical note: This element is triggered when the ScenarioManager receives a CreateInvoice message sent by a pipeline chain that is invoked by the InvoiceManager’s addInvoice() method. For more information, see the Generating Invoices chapter in the Core Commerce Programming Guide.
