For your reference the required permissions are documented in the Windchill Help Center (WHC) in the "Permissions Required for Moving Objects" topic (http://www.ptc.com/cs/help/windchill_hc/wc100_hc/index.jspx?id=AccessControlChp_ReqPermissionMoveObj&action=show)
As well as in this article:

As an FYI, in many cases, the permissions required to perform certain actions can be found in the WHC for 10.x
