Implementation of Interfaces (BOR) 
You use this function to define the interfaces that your BOR 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.
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.
Note
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.
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.
You can add other interfaces to your object type. Position the cursor on the entry on a blue background with the component name Interfaces and select
. This displays a selection list in which you can choose the interfaces your object type is to support.
