Hi,

The structure of the ABAP programs is

1.Define tables which we used in the program,using TABLES

2.Define type-pools using TYPE-POOLS.

3.Define types using TYPES for defining structures

4.DATA

5.SELECTION-SCREEN.

6.SELECT statement.

7.WRITE statement.

Reward points,

Thanks,

hi,

ABAP is an event-driven programming language, and as such is suited to processing user dialogs. The

source code of an ABAP program consists of two parts:

Declarations

Declarations include the statements for global data types and objects, selection screens, and (in ABAP

Objects) local classes and interfaces within the program.

Processing Blocks (indivisible program units)

Each processing block must be programmed as a single entity. There are two basic kinds of processing

blocks:

Event Blocks:

Event blocks are introduced by an event keyword. They are not concluded explicitly, but end when the

next processing block starts.

Dialog Modules and Procedures:

Dialog modules and procedures are introduced and concluded using keywords.

The contents of all processing blocks form the processing logic.

When you generate the program, these parts are compiled to form the load version. This is interpreted at

runtime.

PROGRAM sapbc402_rund_test.

TYPES: ...

CONSTANTS: ...
