Hi,

TYPE REF TO is referring to a class name and only TYPE is defining data type.

You can create an object for a class by defining object using type ref to.

hi

data: r type referrence

<b>it declares data r of type reference.

example: itab type mara.</b>

"it declares internmal table otab of type mara

data : r type REF TO reference.

<b>it declares an object r of a class <b>reference</b></b>

eg

data ; obj type ref to cx_root.

it creates an object obj of a class cx_root

hope it clears ur doubt..

Hi

data : r type reference.

this is used to define/declare a variable with reference to a already existing data element or data type . we use this in normal ABAP programing

data : r type REF TO reference.

This is used in OOPS ABAP programming.

To reference a class we use this

see the example

first create the class zcl_test in SE24 and then declare in program as

DATA: obj_cust TYPE REF TO zcl_test.
