To view the properties of the Notify Approver subprocess, select its process activity in the navigator tree, then choose Properties from the Edit menu. The Notify Approver subprocess has a result type of PO Document Approval Action Process, indicating that when the subprocess completes, it has a result of Approve, Approve and Forward, Forward, Reject, or Timeout. These results correspond to the lookup codes in the PO Document Approval Action Process lookup type, in the PO Standard item type.

This subprocess activity is not runnable, indicating that it cannot be initiated as a top-level process to run, but rather can be run only as a subprocess when called by a higher-level process.

The subprocess begins at node 1.

Node 2 sends a notification to the approver that the document requires approval.

If you have entered a Timeout number in the Properties window for node 2, node 12 sends a reminder notification to the approver. The Timeout number indicates how long the workflow waits before sending the reminder if the approver does not respond. If you have entered a Timeout number for node 12, node 22 sends another reminder. If you have entered a Timeout number for node 22, the workflow ends (times out) at node 33.

Depending on whether the approver responds with Approve, Approve and Forward, Forward, or Timeout, this subprocess sets the correct forward-to and forward-from information: nodes 9, 19, and 29 set this information after an Approve action; nodes 4, 14, and 24 after an Approve and Forward action; nodes 7, 17, and 27 after a Forward action; and node 32 after the subprocess times out if a Timeout is provided.

The PO Approval process, in which this subprocess is contained, behaves differently depending on how the approver responds here-with Approve And Forward, Approve, Reject, or Forward.
