ItemAction is the right click options, and contains only guids. I tied that to the vitem table below:
select vI.name, ia.ItemGuid
from vItem vi
join ItemAction ia on ia.ItemGuid = vi.Guid
So, the issue I see is joining\linking this to the security permission\role privilege tables which are:
SecurityRole
SecurityPrivilegeTrustee
SecurityPrivilege
None of which appear to be associated to the item actions.
