A separate rule creation for Direct PO approval in DocumentApproval

Hi,

We have a request to add a new rule to the Document Approval workflow. The requirement is that if a PO is a Direct PO, it should route to the Director of Procurement and the Associate VP for approval. We usually use PO's associated with a Requisition unless it is emergency or having any issues with submitting a Req. In that case, we create a direct PO and enter all the details along with Requestor, department etc.

We are attempting to create this rule based on the Requisition Number. If the Requisition Number is null on the PO page, the PO should be treated as a Direct PO and routed to the Director of Procurement and Associate VP for approval. Otherwise, the system should follow the existing approval workflow.
