Receipting Controls

Summary: Can purchasing be set up to add controls so that orders can only be part receipted?

Content (required): We often raise high value annual purchase orders for services, as the services are fulfilled the requester must receipt up to the value of the months service and the supplier issues part invoices which are matched and paid periodically.

This approach presents two risks: 

• The receipt for the full years spend can be accrued in one period
• The supplier can receive payment for any matched invoice up to the full value of the order

Is it possible to add controls so that requesters can only part receipt purchase orders, perhaps with percentage tolerances or other methods?
