To view the properties of the Forward PO subprocess, select its process activity in the navigator tree, then choose Properties from the Edit menu. The Forward PO subprocess has a result type of PO Approval Action and Doc Verification, indicating that when the subprocess completes, it has a result of Invalid Action or Valid Action. These results correspond to the lookup codes in the PO Approval Action and Doc Verification 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.

If the Find Approver subprocess activity (outside this subprocess, in the overall workflow) finds an approver, this subprocess forwards the purchase order to the next approver.

Node 2 checks if the purchase order is pre-approved (it has been approved by the final approver, but also forwarded to an additional approver; or it has been authorized for approval but funds have not yet been reserved for it, if you use encumbrance accounting). If it has not been pre-approved, node 4 forwards the purchase order with a status of In Process. If it is pre-approved, node 8 forwards the purchase order with a status of Pre-Approved. The PO Approval workflow still considers a document pre-approved until the subprocess Reserve Before Approve or the subprocess Approve PO sets its status to Approved.

After the document is forwarded, nodes 6 and 10 retrieve purchase order information and other internal workflow attributes, in case these have changed.

If the Document Approval Manager fails at node 4 or 8, the notification activity at node 5 or 9 sends a notification of the failure to the person who forwarded the document. Once the Document Approval Manager is restarted successfully, the workflow continues if the approver or system administrator responds to the notification with Retry.
