Hello - we recently deployed the address data management solution to our (11.3) enterprise portal. Our entire enterprise geodatabase is in dbo schema, and I am a dbo - when I attempt to edit the master street name table, I receive an error regarding "EXECUTE" permissions. From what I'm reading, it seems there are at least two fixes for this, one of which is to create an editor role with execute permissions for the addressing dataset, and another is to create a schema specifically for the addressing data and assign the tables, procedures, etc to that schema.
It's been a little challenging to figure out the best route. How are other folks handling this?
