Top-level binding refers to the use of a global object that defines a namespace for further objects. Top-level binding is achieved by transferring a name to the NAME_PROP parameter of the BIND methods.

The global object is based on the predefined class, SAPAbapRootClass.

If a value is not transferred to the NAME_PROP parameter of the BIND methods, binding is carried out directly to a property of the root object (or of a global variable) of the context.
