Abstract: A system and method for customizing an interface, or the set of methods, of a business object by pre-defining a number of parameters and fields available to the methods of the business object using a visual customization tool is provided. The interface of the business object consists of the set of methods available to it. The interface is customized such that only the necessary methods, parameters and fields are made available for programming. The set of methods is displayed in a menu-driven format through a graphical user interface. The user selects the method to customize, and the set of parameters available to that method is displayed. Then the user selects the parameters that are intended to be used, and the fields available to those parameters are displayed. The user can preset certain static fields to constant values. After customization, the underlying code of the method is generated automatically and saved.
