passing a internal table from method

[Former Member]

Hi All,

I am using Object Oriented Programming in my program.

I want to pass a Internal Table from a method calling statement written in a start-of-selection.

Can any one give me the syntax for

1. Declaring a method with importing parameter as internal table.

2. Syntax for Method Implementation

3. Syntax for calling the method from start-of-selection.

helpful answers are rewarded.

Hi Manoj,

In program which you have mentioned no where call method statement is using exporting statement with internal Table.

Here is a simple example.

 report zrich_0001.

*---------------------------------------------------------------------*
*       CLASS lcl_app DEFINITION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
 class lcl_app definition.

   public section.

     types: t_t001 type table of t001.

     class-data: it001 type table of t001,
                 xt001 type t001.

     class-methods: put_data importing im_t001 type t_t001,
                    write_data.

 endclass.


*---------------------------------------------------------------------*
*       CLASS lcl_app  IMPLEMENATION
*---------------------------------------------------------------------*
*       ........                                                      *
*---------------------------------------------------------------------*
 class lcl_app implementation.

   method put_data.
     it001[] = im_t001[].

   endmethod.

   method write_data.
     loop at it001 into xt001.
       write:/ xt001.
     endloop.

   endmethod.

 endclass.

 data: itab type table of t001.

 start-of-selection.

   select * into table itab from t001.

   call method lcl_app=>put_data( itab ).
   call method lcl_app=>write_data.

Hi Azaz,

1. Declare the parameter as follows in the parameter list of the method :

Parameter : t_table

Type : Exporting or Changing

Typing Method : Type

Associated Type : Table Type

2. Double Click the method name in SE24 and write the code.

3. CALL METHOD CL_GUI_FRONTEND_SERVICES=>FILE_EXIST

EXPORTING

FILE = SOURCE

RECEIVING

RESULT = RC

EXCEPTIONS

CNTL_ERROR = 1

ERROR_NO_GUI = 2

WRONG_PARAMETER = 3

others = 4.

Hi,

Calling Method is similar to calling function Module.

CALL METHOD cl_gui_frontend_services=>gui_download

exporting

filename =

• IMPORTING

• FILELENGTH =

changing

data_tab = <b>( this is ur internal table name )</b>* EXCEPTIONS

• FILE_WRITE_ERROR = 1.

<b>In OO ABAP u avoid creating table with header line</b>

Best way to call method is to use <b>PATTERN</b> Button

1) Click Pattern Button

2) Select Abap Object Pattern

3) Enter

4) Select Call Method

5) Enter instance name ( i. e used for create object ) ( No need for static method like gui_download )

6) Enter Class / Interface name

7) Enter Method Name

done.

<b>passing value to method is similar to FM.

Creating internal table for Method

any TYPE ........SAY TY_Intern

Then Syntax Should Be

DATA : OO_INTERNAL_TABLe type table of TY_Intern.

pass this to the Method.

Hope This will solve ur problem.
