If you extend (add new ABL methods to) a SmartDataObject, to access these extensions you must access the SmartDataObject as a separate ProcObject you create in ProxyGen. This allows you to directly access the SmartDataObject as an ABL persistent procedure with complete access to its public internal procedures and user-defined functions. For more information on accessing a SmartDataObject as a ProcObject, see OpenEdge Development: Open Client Introduction and Programming.
