Use the Properties tab to add properties and methods to your SmartObject. If you selected a standard SmartObject, you do not have the ability to add methods because the standard methods (Create, Save, Load, GetList, and Delete) are added for you using SmartBox. When you're creating Advanced SmartObjects, you can add both properties and methods. You are also not limited to SmartBox, and you can use one or more existing service objects as well as SmartBox.
