BAPIs offer a stable, standardized interface for integrating third-party applications and components in the Business Framework. The interfaces are defined within the SAP initiative with customers, partners, and leading standardization organizations.


A BAPI is basically an entry gate to the R/3 System, while R/3 offers access to business data and processes.

A business object in the Business Object Repository (BOR) can have many methods from which one or several are implemented as BAPIs. (Recall that a “method” is an operation that can be performed on a Business Object that provides access to the object data..)

Some BAPI functions:

• Create objects
• Display attributes of objects
• Change attributes of object

A BAPI is assigned to one and only one business object.
