DATA is not a predefined data type in ABAP. It is a keyword used to define variables.

For eg

DATA: text type C, number type i.

The table below shows the predefined ABAP types.

Type Description

b 1 byte integer (internal)

c Text field

cursor Database cursor

d Date field

f Floating point number

i 4 byte integer

n Numeric text

p Packed number

string Text string

s 2 byte integer (internal)

t Time field

x Byte field

xstring Byte string

Hi vinutha,

Data is not a predefined data type..but it is a predefined type. It is used to declare a variable of any data type.The declared data object(varible) is visible within the current context as of this position.

You can use DATA Statement in two ways

DATA: spfli_wa1 TYPE spfli,

spfli_wa2 LIKE spfli_wa1.

Hope this helps u.

Hi,

any object will be defined as as generic reference variable:

DATA: numref TYPE REF TO DATA,

number TYPE I VALUE 123.

FIELD-SYMBOLS: <fs> TYPE ANY.

GET REFERENCE OF number INTO numref.

ASSIGN numref->* TO <fs>.

such generic reference variable can contain references to data objects of any type. In that example a reference to data object NUMBER will be created and then the data object will be assigned to <FS> with the dereference operator ->*

Using the REF TO addition, you declare a reference variable ref. The specification after REF TO specifies the static type of the reference variables. The static type limits the set of objects to which ref can point.

Example

In this example, an object reference oref and two data references dref1 and dref2 are declared.

CLASS c1 DEFINITION.

PUBLIC SECTION.

DATA a1 TYPE i VALUE 1.

ENDCLASS.

DATA: oref TYPE REF TO c1,

dref1 LIKE REF TO oref,

dref2 TYPE REF TO i.

Hope you are clear now..

Reward points if u find this helpful..
