Hello Reema jain,

Just go in the se24 and edit your class.

In the tab 'Attribut'

add the name of your attribute, if it is an instance attribute or a constant..., the visibility (public/protected...) and the type (enter here the type of your internal table).

Regards,

Walter

Hello Reema

If your instance attribute is private then you can use private table type definitions to define an itab, e.g.:

" Type definition in private section
TYPES: 
  ty_t_knb1  TYPE STANDARD TABLE OF knb1.

" Define your instance attribute using this type definition, e.g.:
MT_KNB1   (instance, private)  TYPE ty_t_knb1.

However, if your itab should be either protected or even public then you must use a table type defined in the DDIC, e.g.:

MT_RETURN  (instance, public)  TYPE bapirettab (= table type of BAPIRET2).

Uwe

Hi Reema,

The recommended way is to make a table type for your internal table.

If you know the structure of your internal table, make a similar structure in SE11 (say ZSTRUCTURE).

Next go to SE11 again and create a table type :

Choose Data Type and give a name(say ZTABLETYPE) and press Create, next choose the radio-button for Table Type.

In the next screen, give your structure name(ZSTRUCTURE) as the Line type.

Activate this table type.

Now go to your global class in SE24, go to attributes.

Add a public attribute of TYPE ZTABLETYPE and this attribute will be an internal table of the type you wanted.

Hope this helps.

Hai Reema Jain,

Just like declaring a data object(variable),You can declare them in your global class.

Example:

CLASS c1 DEFINITION.

PUBLIC SECTION.

METHODS m1 IMPORTING p1 TYPE string.

PRIVATE SECTION.

DATA a1 TYPE string.

<b> DATA:

BEGIN OF ITAB ,

FIELD1 TYPE C,

FILED2 TYPE I,

END OF ITAB,

T_ITAB LIKE STANDARD TABLE OF ITAB.</b>

METHODS m2.

ENDCLASS.

CLASS c1 IMPLEMENTATION.

METHOD m1.

a1 = p1.

m2( ).

ENDMETHOD.

METHOD m2.

DATA a1 TYPE string.

a1 = me->a1.

write:

/ a1.

ENDMETHOD.

ENDCLASS.

DATA:

OREF TYPE REF TO C1.

START-OF-SELECTION.

CREATE OBJECT OREF.

CALL METHOD OREF->M1('abc').

Hope this helps you.
