internal tables: It are tables for holding data during runtime

In ABAP, internal tables fulfill the function of arrays. Since they are dynamic data objects, they save

the programmer the task of dynamic memory management in his or her programs.

Internal table will usually be associated with a structure or work area.

Internal table cannot be accessed outside the program environment.Accessing Internal Tables

You access internal tables line by line. You must use a work area as an interface for

transferring data to and from the table.Grant Taylor

Creating Internal Tables

There are two ways by which you can create internal tables1. First create an internal table data type using the 'TYPES' statement and then create

a data object referring that data type.

2. Create an internal table data object directly with the 'DATA' statement.

TYPES: BEGIN OF LINE,

COLUMN1 TYPE I,

COLUMN2 TYPE I,

COLUMN3 TYPE I,

END OF LINE.
