U can use methods for vreating ALVs.

There is a method named set_table_for_first_display in OOP Concepts.

Use this Object Oriented Approach for ALV Creation

Calling the method set_table_for_first_display

*----

CALL METHOD cust_alv->set_table_for_first_display

EXPORTING

is_layout = gst_layout

CHANGING

it_outtab = gt_list

it_fieldcatalog = gt_fcat

EXCEPTIONS

invalid_parameter_combination = 1

program_error = 2

too_many_lines = 3

OTHERS = 4

IF sy-subrc <> 0.

MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno

WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.

ENDIF.

Object Creation and all

Creation of Object for Container

*----

CREATE OBJECT cust_container

EXPORTING

Hi Suddu,

Go to the following link which gives you sample codes with brief description of the programs.

<a href="http://www.sapdev.co.uk/reporting/alv/alvscr.htm">http://www.sapdev.co.uk/reporting/alv/alvscr.htm</a>

Then coming to steps for creation of ALV in OOABAP.

1. Create a program in se38 and just activate it without any code for now.

2. Go to module pool and create a screen, put a custom container control on to the screen. (You will find this control on right side tool box).

3. Give a name to the control created in step 2.

4. Activate the screen.

5. Come to the program declare two variables to hold instances of 2 classes CL_GUI_CUSTOM_CONTAINER, CL_GUI_ALV_GRID.

6. create an instance of the class CL_GUI_CUSTOM_CONTAINER passing container name created in step 3.

7. create an instance of the class CL_GUI_ALV_GRID passing INSTANCE VARIBALE name created in step 6.

8. using the ref. variable of previous step call method SET_TABLE FORFIRST_DISPLAY method and pass structure name and internal table containing data.

9. then call screen created in step 2.

see my next post for the program code.

Hey... execute the program . You are there with your OOALV.

Aleem.
