Difference between TYPES and DATA...

Hi frnds,

What is the difference between TYPES and DATA.... I have given example below....

TYPES: BEGIN OF I_EKKO,

EBELN LIKE EKKO-EBELN,

AEDAT LIKE EKKO-AEDAT,

BUKRS LIKE EKKO-BUKRS,

BSART LIKE EKKO-BSART,

LIFNR LIKE EKKO-LIFNR,

END OF I_EKKO.

DATA: BEGIN OF I_EKKO,

EBELN LIKE EKKO-EBELN,

AEDAT LIKE EKKO-AEDAT,

BUKRS LIKE EKKO-BUKRS,

BSART LIKE EKKO-BSART,

LIFNR LIKE EKKO-LIFNR,

END OF I_EKKO.

Thanx in Adv,

Reg,
