Use PO Requester Position to drive AP Matching Hold Release workflow

Summary: We are using Position Tree logic based on the PO Requester to drive the PO Approvals. We want to use the same logic for AP Matching Hold Release workflow

Content (required): We (customer Katoen Natie) are using Position Tree logic based on the PO Requester (showing on the PO Line/Distribution) to drive the PO Approvals workflow. We want to use the same logic for AP Matching Hold Release workflow but the Invoice Line Requester does not have a Position ID available to use in the approval rules. The only field available is the Requester on the invoice header but that does not populate automatically so it is not usable.
