Restrict changing status on PO

Question

Is there a way to prevent certain users from changing the status of a PO from "Held" to "Complete".  Our Purchasing department generally puts a PO on hold in case other data is required before actually saving the PO to be submitted to the vendor.  But, another user may go into ME22N, make changes, and click Save instead of Hold. Are there some sort of blocks or messages that can be generated when a user changes the status from "incomplete" to "complete"?
