A purchase requisition can be initiated following a requirement/need already studied by one or more vendors.
For example, for IT consulting needs, quotations are requested and when the choice is done, the customer begins its purchase requisition / purchase order creation process.
So the idea would be to be able to send the quote in MF Capture to go through a verification step (like invoices in fact) before retrieving the imae and metadata throughout the order process.
This step would then become the first step of the procurement flow and would offer a significant time saving.
