BAPI Quick Start
[ Return to Table of Contents ]
BAPI (Business Application Programming Interface) is a set of interfaces to object-oriented programming methods that enable a programmer to integrate third-party software into the proprietary R/3 product from SAP. For specific business tasks such as uploading transactional data, BAPIs are implemented and stored in the R/3 system as remote function call (RFC) modules.
A good place to get started is this Introduction to BAPIs presented by sappoint.com.
SAP also provides this in-depth BAPI User Guide to help you master the basics. Terminology, rules for usage and prerequisites are included.

BAPIs, RFC and IDOCs- who's on first?
[ Return to Table of Contents ]
BAPIs, RFCs and IDOCs are often confused. This section will help you to understand how RFCs relate to BAPIs.A BAPI is a business object. An RFC is functional code. IDOCs OR intermediate documents are standard data structures for electronic data interchange (EDI) between application programs. IDocs are used for asynchronous transactions: each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database.
Included here is expert advice from SearchSAP.com Ask the Expert panelists Thomas Schuessler and Axel Angeli.
