Addresses of Business Address Services are distributed as independent objects using specific IDocs. The BOR object types for the three address types areBUS4001 (company addresses), BUS4002 (personal addresses) and BUS4003 (workplace addresses).
Addresses are distributed separately, but never independently of the address application object. They are not distributed through their key (internal address or person number) – which is only valid locally in each system – but through their owner (for example, the customer or the vendor). The key of the primary object is unique across all systems and used to determine the local address number in the target system: The address IDoc also contains information on the object type (for example, the customer) and the object key (for example, the customer number.)
This information is used by a callback function module of the application to determine the address number (or person number).
