I have a file geodatabase and I have a Feature Class named CSOs , field name called Estimated Volume. I setup two subtypes Called 1 Active , 2 Closed. When i go into the Workspace Domains and create one coded Domain Estimated Volume the values for the coded domain is 0 - Less than 100gal , 1 - 1000- 10000gal , 2 - More than 10000gal. Everytime I enter the values ArcCatalog it says failed to update one of the domains, the existing domain types does not match that of the updated domain.
Can you share a Screenshot of the Database Properties> Domains window.
