Defining Back-End Interface 

Purpose

In this process, the developers define the back-end part of the mobile application by enhancing existing or creating new Business Application Programming Interfaces (BAPIs) and BAPI wrappers. The BAPIs are the interface between the SAP NetWeaver ASand the back-end functions and data.

The developers must identify the existing BAPIs to establish what data is provided by the back-end system. If any required data is missing, the developers can create new BAPIs to access it.

Use of the Process

This IT process is part of the following IT scenario:

IT Scenario	Scenario Variant
