Hi

http://help.sap.com/saphelp_nw04/helpdata/en/fc/eb2fb2358411d1829f0000e829fbfe/content.htm

TYPES :

BEGIN OF type_s_tab,

a TYPE i,

b TYPE i,

END OF type_s_tab.

TYPES :

t_c(50) TYPE c.

the above declaration does not have any memory assigned to it

DATA :

itab TYPE

STANDARD TABLE OF type_s_tab.

DATA :

w_c TYPE t_c.

The above declarations are objects of TYPE type_S_tab and t_c

and memory is assigned to it

DATA :

w_char LIKE w_c.

The above declaration of the object is referring to the type of w_c which is occupying 50 characters.

Hi

Types: It is the statement used to define our own local data types in the program. Types won't occupy

any memory at run time.

Data: It is the statement to declare a local variable in the program. Data objects occupy memory at

runtime.

Hope it helps.
