Messages with severity level 11 indicate that Adaptive Server cannot find an object that was referenced in the command.
This is often because the user has made a mistake in typing the name of a database object, because the user did not specify the object owner’s name, or because of confusion about which database is current. Check the spelling of the object names, use the owner names if the object is not owned by you or “dbo,” and make sure you are in the correct database.
