How to return an internal table with methods ?

Hi,

I am an Java programmer and very new to ABAP.

How do I return a internal table with a method? I have the table GP1_PRODUCTS and want to return a copy of this table as an internal table called PRODUCTS.

Here is my code that does not work:

class PRODUCTS definition
  public
  final
  create public .

public section.
*"* public components of class PRODUCTS
*"* do not include other source files here!!!

  methods GET_PRODUCT_LIST
    returning
      value(PRODUCTS) type GP1_PRODUCTS .
protected section.
*"* protected components of class PRODUCTS
*"* do not include other source files here!!!
private section.
*"* private components of class PRODUCTS
*"* do not include other source files here!!!
ENDCLASS.



CLASS PRODUCTS IMPLEMENTATION.


* <SIGNATURE>---------------------------------------------------------------------------------------+
* | Instance Public Method PRODUCTS->GET_PRODUCT_LIST
* +-------------------------------------------------------------------------------------------------+
* | [<-()] PRODUCTS                       TYPE        GP1_PRODUCTS
* +--------------------------------------------------------------------------------------</SIGNATURE>
method GET_PRODUCT_LIST.


 DATA: it_products TYPE STANDARD TABLE OF GP1_PRODUCTS.


 select * from GP1_PRODUCTS into table it_products.

 PRODUCTS = it_products.


endmethod.
ENDCLASS.

You have to create a table type for your table GP1_PRODUCTS.

If you use global class (created in SE24), than:

Create a Table Type in SE11

Go to SE11, Enter a name like ZPRODUCTS in the Data Type

There will be popup when you press the Create button to decide a type. Select the Table Type

Enter GP1_PRODUCTS in the Line Type.

* method declaration
  methods GET_PRODUCT_LIST
    returning
      value(PRODUCTS) type ZPRODUCTS.

If you use local class:

TYPES: ty_products type standard table of GP1_PRODUCTS..

* method declaration
  methods GET_PRODUCT_LIST
    returning
      value(PRODUCTS) type ty_products
