SAP BAPI COMPLETE LIST
BAPIs (Business Application Programming Interfaces) are the standard SAP interfaces. They play an important role in the technical integration and in the exchange of business data between SAP components, and between SAP and non-SAP components. BAPIs enable you to integrate these components and are therefore an important part of developing integration scenarios where multiple components are connected to each other, either on a local network or on the Internet. BAPIs allow integration at the business level, not the technical level. This provides for greater stability of the linkage and independence from the underlying communication technology

Business Add-Ins are a new SAP enhancement technique based on ABAP Objects. They can be inserted into the SAP System to accommodate user requirements too specific to be included in the standard delivery.
