Restrict Requester to Override Price But Allow Buyer to Override.

Content

Dear Team - We have a need on the Allow price override, we should keep the flag allow the price override in BPA, but our requirement is whenever a requestor is creating a requisition referring the BPA he must not be able to change the price on the line, but when the req is converted to PO referring the same BPA, the buyer must be able to change the price. In a nutshell,  can we stop the requestor from changing the price but then allow the buyer to change it. ?? Is it possible?
