Auto Approval of Purchase Orders Created from Requisitions - 11i

What are different options for setting up Autoapproval for PO's created from requisitions?   We have thought of following options:

1. Giving AutoCreators / Buyers approval limits to approve (take the requisition approval as the proper approval), but those people could generate new PO's without proper authorization or modify.

2. Modify Workflow to autoapprove PO's created from Requisitions and let any revisions / new PO's go through standard PO Approval Workflow

Thank you.

Hi,

I have a couple questions to help understand the business scenario.    Are you referring to POs created manually via the AutoCreate (or via the Document Builder in the Buyer Work Center)  , and then the user submits the PO for approval and you want them self approved?    Or are these POs created automatically via the PO Create Documents workflow from approved requisitions?
