I'm using LL8.1.3 and SQL 7.I have lots of drawings and documents owned by 'Admin' and want to change their owner to a real user.I think LiveReport can change the ownergroup and its permission. Right?But I don't know whether 'Admin' owner can be changed by LiveReport.Any help is appreciated.Shirley
