The Business Object Repository

• The Business Object Repository is the central access point for the SAP business object types and their BAPIs.

The Business Object Repository provides following services in the BAPI context.

• Allow an object-oriented view  of all data and processes in an SAP System arranging the various business object types according to the component hierarchy .
• Transaction Code : BAPI.

• BOR contains all the relevant information on the SAP business object types, their key fields , and their BAPI methods that is needed to integrate the correct object type definition and BAPI calls in an Application program.

• Any interface changes carried out in the BOR are automatically checked for syntax compatibility against the associated development object in the ABAP Dictionary.
• BOR manages BAPIs in release updates.

1. BAPI interfaces enhancements made by adding parameters are recorded in the BOR. Previous interface version can thus be reconstructed at any time.
2. When a BAPI is created , the release version of the new BAPI is recorded in the BOR.
3. The same applies when any interface parameter is created.
