When you display the Process window for the Supplier: Get Order Details subprocess, you see that the subprocess consists of five unique activities, one of which is reused to make up the six activity nodes that appear in the workflow diagram. 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 agent details for the intended outbound and inbound agents to send responses to the buyer. Next, the process retrieves the item number and item description of the ordered item from the purchase order. When both the item number and item description have been retrieved, the subprocess ends.
