Business Address Services (BAS) offer functions for managing addresses in applications. You can store and further process addresses, using different address types. An address is subordinate to an associated application object (such as a customer, a purchase order, or a plant).

BAS Tables

All addresses are stored in tables of Business Address Services. To be able to access addresses later on, the application stores only the key of an address in its application table.

Some applications that used to store address data in their own tables in previous releases still do so and keep the address data redundantly in their own tables.

The application program never accesses the BAS tables directly, but uses function modules to access addresses. Using the table entries, however, you can verify if the address data has been updated correctly. The address data is stored in three tables:

Tables of Business Address Services for address data

An address number in table ADRC or a person number in table ADRP is unique. However, both a person number and an address number can occur more than once in table ADCP . A person number occurs more than once if a person has multiple addresses, and an address number occurs more than once if a company address is referenced by multiple persons.
