Implementation of Interfaces
Use
You use this function to define the
interfaces that your object type supports. SAP supplies interfaces that you can use when defining your own object types.Using interfaces standardizes the definition of the object type components.
Integration
Using an interface guarantees that the object type fully supports the methods (with all parameters and all exceptions), attributes and events in the interface.
If your object type is to support an
abstract interface, you must redefine and implement the inherited attributes and methods.
When redefining methods, you can only change the implementation of the method in the implementation program. The interface (parameters and exceptions) can only be extended.
Features
All objects types support the
standard interface. This contains the interfaces Check existence and Display. The functionally related attributes, methods and events already defined in the interfaces are hence available to the object type.Activities
You can add other interfaces to your object type.
Position the cursor on the entry with a blue background that has the component name Interfaces, and choose
. This displays a selection list in which you can choose the interfaces your object type is to support.
