What is ABAP/4?

ABAP/4 – “Advanced Business Applications Programming

Language 4th Generation”

• ABAP/4 was developed using C++

• SAP R/3 was made using ABAP/4

• ABAP/4 is the Development Tool of SAP R/3

4

ABAP is a Tools

ABAP/4

• It is used by SAP developers to build the transactions that make up the R/3 application.

• It is also used by corporations to customize their R/3 applications.

• ABAP/4 is not used by customers of SAP to develop complex applications from scratch, but is used instead to provide additional business functionality

5

The roles of ABAP/4 in SAP R/3

Two most common uses for ABAP/4:

1. Producing Custom ReportsA REPORT is an ABAP program that reads specific data from SAP’s database and then displays the data via a computer screen or a printed page.

2. Developing Custom Interfaces for SAPAn INTERFACE is an ABAP program that moves data into SAP, or reads data from SAP and writes it out to a system file to be transferred to an external computer system, such as a legacy mainframe.

6


Other uses for ABAP/4

1. Conversion Programs– Change data into a format usable by SAP

2. Custom Transactions– Similar to SAP standard transactions, but are

written to fulfill some business functions not provided by SAP standard transactions.

7


Final Notes:– From an ABAPer’s Perspective,

SAP is nothing more than a collection of database tables.

– The main concern of an ABAPer’s is how to present and modify these tables and their data as required by the user.

Important Note!

• The Programs that you’ll be making are saved as Local Objects simply because they will never be transported from your Development Server to your Production Server.
