I am having trouble deleting a feature class in SDE. I am the DBO for the database, and there are a couple of feature classes in there under a user name that I need to delete. In trying to set permissions, I was given different levels to see what I could and could not do. In doing this. I created a couple of feature classes as tests, and now they won't delete. They are titled ADS/username/layer name. When i'm connected as the DBO, I try to delete them, and I get an error saying that they can't be deleted because I'm not the owner. My thought is that being an owner should allow me to delete these without problem. I have attached a screenshot of the errors that I'm getting.
Thanks in advance for any help on this.
