I'm going to review one book that explain about ABAP programming and easy to understand. I have used this book for my courses at my uni and it is really helpful. This is because it giving a lot of sample of codes and the explaination for each codes is easy to grab. You also can install MiniSAP at your PC and start to learn ABAP without paying high fees for ABAP course. Therefore, you will save your money and also your time because you can learn ABAP at your own place. You can find the book description below and grab one when it is still available.

ABAP (Advanced Business Application Programming) is a powerful programming language created specifically for developing SAP applications. ABAP Objects is the new object-oriented generation of this language, designed to respond to the needs of SAP's future strategies and environments.

Written by two leading experts and approved by SAP's ABAP Language Group, ABAP Objects provides an in-depth and comprehensive introduction to SAP application programming for Release 4.6. The focus is on ABAP Objects, which is treated here not as an add-on, but as an integral part of the ABAP language. An indispensable guide for novice and experienced programmers alike, ABAP Objects includes coverage of these essential topics:

The new ABAP Workbench and the most important features of the ABAP language.
The fundamentals of ABAP programming, including the ABAP runtime environment.
The core ABAP language elements.
The two ABAP programming models - classical and object-oriented - and their relevant statements.
Advanced concepts of OO programming with ABAP Objects.
Programming the SAP user interface.
Database access with OpenSQL.
ABAP glossary and a complete list of system fields.

The book also includes two CDs carrying a fully operational SAP Basis System, and containing all the example programs from the book.

This is a definition I found from the internet: ABAP (Advanced Business Application Programming) is a programming language created by the German software company SAP. It is currently positioned as the language for programming SAP's Web Application Server, part of its NetWeaver platform for building business applications. Its syntax is somewhat similar to COBOL.

From my opinion, ABAP is same like C++. I think the logic that be applied for C++ program also can be used while writing an ABAP report but a strong fundamental in SQL statement would be some advantages to the programmers because ABAP report is all about retriving date from database and populate it as a report to the users.

The basic keyword for ABAP are:

data:
parameters:
tables:
write:
write:/
start-of-selection.
end-of-selection.

This is a simple program of ABAP:

data: num1 type i,
num2 type i,
num3 type i.

start-of-selection.
num3 = num1 * num2.

write:/ "The answer is:", num3.

end-of-selection.
