I would like to know if it's possible in BPM to drive an invoice approval supervisory workflow starting out with a Requisition Requester if the invoice is matched to a PO.

Use Case:

The company has invoices that are matched to a Purchase Order. All Purchase Orders require a requisition. When Accounts Payable receives and invoice, they match to the PO and then find out who the requisition requester is on the PO. The input that person as the invoice requester so the there is an approval by the requisition requester and/or that person's manager.
