I am having trouble determine which privilege allows some to only close the opportunity as won. Basically our sales team will create the opportunity, however, they will not be allowed to close them as WON. This role will be handled by a different role. I need to remove that right from the sales security role and give it to another role.

If anyone has an article or can point me in the right direction, I would greatly appreciate it. I feel like I have reviewed every article online :-D
