An object can have different representations, depending on the context in which it is used.
For example, the person Mr. Smith has a particular customer number as a customer of mail order company A and has a particular employee number as an employee of company B. Both numbers refer to the same person.
You use the value mapping function to map different representations of an object to each other. You save the mapping rules for different objects in a value mapping table.
You use value mapping in the following areas of SAP Exchange Infrastructure:
· Java mapping

Mappings.

Message mapping
(see

Functions)
In SAP Exchange Infrastructure, the representation of an object is defined by an issuing agency and an identification scheme (see Identifiers). The representation of an object is not complete until the agency, identification scheme, and value are known.
You can define value mappings in different value mapping contexts, for example, the Integration Directory or the SAP Solution Manager. Different value mapping contexts are of use when you want to transfer value mappings from another context (see Value Mapping Replication Using a Specialist Interface).
You save object representations in a value mapping table.
You have the following options for editing the content of value mapping tables:
· Manual Input using the user interface of the Integration Directory
· Replication from external data sources using a specialist interface
