It means that your database table owner is not the same as the login user. You don't say what database you're using, but the non-Oracle databases permit "login foo" to be mapped to "schema bar" in database X, but since the geodatabase registry works off of login name, it can't tell who the rightful owner is (well, it could, but it would make every other operation so slow, the net result would be useless). So enterprise geodatabases require that the owner schema must be the same as the owner user, which must be the same as the login user.
You'll need to reload the data to clear this error.

PS: Please edit your post ("Edit" menu choice on the upper right), so that "schme dont" is "schema don't", so others can use the exact error message to locate this question.
