We need to be able lock down one cost plan so that no one except the administrators can change it. Our project managers have been granted the "Cost Plan - Edit All" right because we typically do want them to manage their own plans. However, in certain instances we need one special cost plan that they can't change. It didn't look like I could manage this through security, so I thought that maybe I would use a process to lock the attributes of the cost plan and then just give administrators the ability to run that process against the cost plan in question. However it appears that I am unable to use a cost plan as a primary object on a process. Does anyone have any ideas on how we could achieve this? We are On Demand customers, running 12.0.6.
