Is it possible to use subprograms that contain an object data as a service. I did notice that when I try to disclose a method of a class (which is basically a subprogram that shares the state of an object), I am unable to use this method (subprogram) as a Natural RPC service (it seems that the subprogram itself can only be used within the context of an object). Is this a known issue? Kind regards, Rudolf ---

A Natural subprogram that contains an ODA cannot be called by CALLNAT statement. This implies that this subprogram can also not be called as a Natural RPC service. ---
