I just created a parcel fabric. The fabric I am using has subtypes. The parcels feature class as a field named ParcelSubtype. I tried adding the a subtype to the field as described in the help document. The Addtype geoprocess failed because it could not find a field designated as a subtype. I had to enter design mode and designate the field as a subtype field. Is there a reason why the ParcelSubtype field is not automatically set to a subtype field when a parcel feature is added to a parcel fabric?
