This document provides an overview of common ABAP objects and programming concepts. It begins with a list of T-codes related to ABAP development and editing. It then discusses ABAP programming rules and data types. The document provides examples of variable declaration, operators, and control structures like IF/ELSE and CASE statements. It also covers database access loops and standard SAP tables.

Abap Programming rules :-
1. . (period)
2. abap statements are not case sensitive.
eg: write
WRITE
3.
4. abap is space sensitive
eg: c=a+b. (wrong)
c = a + b.(correct)
5. * (or) " for commenting
* ---> at the begining of the line
" --> middle of the line
