Editing item descriptions in a Sourcing negotiation created from a Purchase Requisition

Hello, I would like to confirm the expected behavior when a Sourcing negotiation is created from a Purchase Requisition.

In this scenario, the line description comes from the requisition and the buyer cannot change it in the negotiation.

My questions are:

• Is it possible to edit the line description directly in the negotiation when it comes from a requisition?
• If yes, what setup or privilege allows the buyer to do this?
• If not supported, should the description be updated in the requisition and then create the negotiation again?

Thank you,

Santiago.
