## Summary of the Buyer: Send PO to Supplier Subprocess

To view the properties of the Buyer: Send PO to Supplier subprocess, select its process activity in the navigator tree, then choose Properties from the Edit menu. This process activity is not runnable, indicating that it cannot be initiated as a top level process to run but must be called from a higher level process.

When you display the Process window for the Buyer: Send PO to Supplier subprocess, you see that the subprocess consists of five 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 subprocess begins at node 1 with the Start activity. At node 2, the process retrieves the name of the order requestor from the purchase order event message. Then the process sends the purchase order to the supplier and notifies the order requestor that the purchase order has been sent. The subprocess ends at this point.
