Summary of the Buyer: Top Level PO Process

To view the properties of the Buyer: Top Level PO process, select the process in the navigator tree, then choose Properties from the Edit menu. This process activity is runnable, indicating that it can be initiated as a top level process to run.

When you display the Process window for the Buyer: Top Level PO process, you see that the process consists of nine unique activities. To examine the activities of the process in more detail, we have numbered each node for easy referencing below. The numbers themselves are not part of the process diagram.

The Buyer: Top Level PO workflow begins when you submit a purchase order from the Buyer Workbench demonstration page, raising the B2B Purchase Order event. Predefined subscriptions add a correlation ID consisting of the prefix PO followed by the event key (the order number), and send the event to the Buyer: Top Level PO process. See: To Initiate the Event System Demonstration Workflow from the Buyer Workbench.

The process begins at node 1 with the Buyer: Receive Create PO Event activity. The process finds a supplier for the purchase order and retrieves the agent details for the intended outbound and inbound agents to send the purchase order to the supplier.

Node 4 is a subprocess that retrieves the name of the order requestor from the purchase order event message, sends the purchase order to the supplier, and notifies the order requestor that the purchase order has been sent to the supplier.

Node 5 is a subprocess that waits to receive a purchase order acknowledgement event message from the supplier. If the acknowledgement is not received within a specified period of time, the subprocess performs a timeout activity to keep notifying the order requestor that the supplier has not responded until the acknowledgement is received. When the acknowledgement is received, the subprocess notifies the order requestor of the acknowledgement.

After the purchase order acknowledgement is received, the top level process waits to receive an advanced shipment notice and an invoice from the supplier. Node 6 is a subprocess that receives the advanced shipment notice and notifies the order requestor that the order has been shipped. Node 7 is a subprocess that receives the invoice and notifies the order requestor that the invoice has arrived. After both of these subprocesses complete, the process ends.
