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.

BAPI

It has advantages over BDC.
1. Upgrade compatibility (4.60 to ECC 6.0)
2. It is not screen based
3. It is online update
4. It is used for remote interfacing.

So we go for BAPI

Purpose

After you have carried out the review of the BAPI concept
and it has been accepted, you can start defining the BAPI
itself.

In this step, you will decide on the names, parameters, and
characteristics of the BAPI and determine the structures in
the ABAP Dictionary, which the BAPI

you have planned and defined these required details can you
start to implement the BAPI and create the required
programming objects.

The table below illustrates where the planned information is
written and how it fits together.

Information in the BOR, Function Builder and ABAP Dictionary


Standardized BAPIs

Use

Some BAPIs and methods provide basic functions and can be
used for most SAP business object types. Such BAPIs are
known as "standardized" BAPIs.

Features

With object methods and especially with BAPIs, you can
differentiate between instance methods and class methods.
Instance methods refer to precisely one instance (one
specific occurrence) of an SAP Business Object type, for
example, to one explicitly specified customer order. Whereas
class methods are instance-independent.

BAPIs for Reading Data

The following BAPIs provide you with read-only access to
data in the associated business object type:
GetList()
With the BAPI GetList() you can select a range of object key
values, for example, company codes and material numbers. The
BAPIs GetList() is a class method.

Programming GetList() BAPIs

Use

With the BAPI GetList() you can select a range of object key
values, for example, company codes and material numbers. The
key values returned by this BAPI can be passed on to another
BAPI for further processing, for example, the BAPI GetDetail().
The BAPIs GetList() is a class method (instance-independent).

Features

Provide all the relevant fields in the interface of the
GetList() BAPI. How complex and extensive you structure the
interface, depends on the requirements the BAPI is to fulfill.
