A representation is defined as the perceptible form of the information carried by a business object.
Representations (for example, messages or documents) are the perceptible carriers of information that are related to business objects.
A single business object can have a number of different representations, but a representation always belongs to one specific business object. A representation may realize one or more business objects. A meaning can be associated with a representation that carries this meaning.
