**Business Application Programming Interface** (**BAPI**) is used in [mySAP](/source/MySAP) to achieve business related functionalities. It is a remote-enabled function module which is provided by [SAP](/source/SAP_ERP). [1]

## Description

BAPIs enable access to SAP functions across formal, stable and dialog-free interfaces. These interfaces can be used by external applications developed by customers and complementary software partners as well as by other SAP applications. Defined as [API](/source/API) methods of SAP Business Object Types, these object types are used within the Business Framework to enable object-based communication between components.

[Business objects](/source/Business_object_(computer_science)) and their BAPIs enable [object orientation](/source/Object-oriented_programming) to be used in central information processing in companies. For example, existing functions and data can be re-used, trouble-free technical interoperability can be achieved and non-SAP components can be implemented. Applications can use BAPIs to directly access the application layer of the R/3 System and, as clients, applications can use the business logic of the R/3 System. BAPIs provide the client with an object-oriented view of the application objects without needing to know the implementation details. BAPIs are always developed by defining scenarios which are used to map and implement system-wide business processes.
