## B2B Purchase Order Event

This event is raised on the Buyer system when you submit a purchase order from the Buyer Workbench demonstration page.

Internal Name | demo.oracle.wf.b2b.po.create
Generate Function | wf_eventdemo.generatexml

Oracle Workflow provides two default subscriptions to the B2B Purchase Order event. The first subscription sends the event message to the Buyer: Top Level PO process in the Event System Demonstration item type when the B2B Purchase Order event is raised locally. This subscription is enabled by default. You should add an outbound agent on the Buyer system and an inbound agent on the Supplier system to this subscription on the Buyer system, to specify where you want the Buyer: Top Level PO process to send the event message.
