Hello. For feature "KhuChucNangP", only the "doiTuong" property has a subtype defined. The default subtype defined for "doiTuong" is "Co So An ninh". So, only these subtypes could been seen as domain list for that feature since this is the only define. That is my understanding here. If I am wrong, please be more precise of where you should see other subtype defined. Please let me know if I miss something. Sebastien Lefrancois [Bentley]
