Dear

Internal types are just like table which you see in Microsoft Word with heading for example

Empno ename job salary deptno

1 SMITH MANAGER 2000 10

2 WARD ANALYST 3000 20

3 ALLEN CLERK 1500 10

4 ZEESHAN PRESIDENT 5000 30

you can get data from tables and put it in internal table for future use. at run time the data i fetch from database into internal tables.

after that you get the data from internal table line by line and process it.

There are three table kinds:

- standard tables,

- sorted tables

- hashed tables

most of the time standard tables are used.

if you want to declare an internal table based on a database table the syntex would be like this

DATA itab_scarr type standard table of scarr.

here itab_scarr is an internal table and has the same columns which scarr table has.

now i will give you an example of internal table

DATA itab_scarr TYPE STANDARD TABLE OF scarr.

DATA wa_scarr TYPE scarr.

SELECT * FROM scarr

INTO TABLE itab_scarr.

LOOP AT itab_scarr INTO wa_scarr.

WRITE: / wa_scarr.

ENDLOOP.

second example

you can also define an internal table on the base of you own type for example

TYPES: BEGIN OF template,

a TYPE c,

b TYPE c,

c1 TYPE c,

END OF template.

DATA itab_template TYPE STANDARD TABLE OF template.

DATA wa_template TYPE template.

wa_template-a = 'A'.

wa_template-b = 'B'.

wa_template-c1 = 'C'.

APPEND wa_template TO itab_template.

wa_template-a = 'C'.

wa_template-b = 'E'.

wa_template-c1 = 'F'.

APPEND wa_template TO itab_template.

wa_template-a = 'G'.

wa_template-b = 'H'.

wa_template-c1 = 'I'.

APPEND wa_template TO itab_template.

LOOP AT itab_template INTO wa_template.

WRITE: / wa_template.

ENDLOOP.

here you find another type that is wa_template that only hold one line at a time you store the value into wa_template then append (insert at the end) it to internal table.

if you want to know the operations on internal table replay be back.
