Check the following examples,they may help u.

BCALV_EDIT_01 This report illustrates the simplest case of using an editable/noneditable ALV Grid Control.

BCALV_EDIT_02 This report illustrates how to set chosen cells of an ALV Grid Control editable.

BCALV_EDIT_03 In this example the user may change values of fields SEATSOCC (occupied seats) and/or PLANETYPE.

The report checks the input value(s) semantically and provides protocol messages in case of error

BCALV_EDIT_04 This report illustrates how to add and remove lines to a table using the ALV Grid Control and how to

implement the saving of the new data.

BCALV_EDIT_05 This example shows how to use checkboxes within an ALV Grid Control. You learn:

(1) how to define a column for editable checkboxes for an attribute of your list

(2) how to evaluate the checked checkboxes

(3) how to switch between editable and non-editable checkboxes

BCALV_EDIT_06 This example shows how to define a dropdown listbox for all cells of one column in an editable ALV

Grid Control.

BCALV_EDIT_07 This example shows how to define dropdown listboxes for particular cells of your output table.

BCALV_EDIT_08 This report implements an ALV Grid Control with an application specific F4 help. The following aspects

are dealt with:

(1) how to replace the standard f4 help

(2) how to pass the selected value to the ALV Grid Control

(3) how to build an f4 help, whose value range depend on a value of another cell. BCALV_GRID_01

BCALV_GRID_02(Example for moving from one list to the other )

BCALV_GRID_03

BCALV_GRID_04

BCALV_GRID_05

BCALV_GRID_06

BCALV_GRID_07

BCALV_GRID_08

BCALV_GRID_09

BCALV_GRID_10

Hi All,

What I needed is ALV list, not ALV grid.

Kindly provide me coding which is related to ALV..

For example, for the ALV using FM to call out, we can use REUSE_ALV_LIST_DISPLAY or REUSE_ALV_GRID_DISPLAY....so in OO ALV, how we can call out ALV LIST?

1. Create a Control (for Custom and Split Containers only)

2. Instantiate a Container Object (in case of Custom and Split Containers, specify the control which is created by us in Screen painter) CREATE OBJECT <Container Object>

3. Instantiate an Object of the kind of report that has to be displayed (List, Grid or Tree). CREATE OBJECT <List/Grid/Tree>. Here we need to specify the Parent Container as the <Container object> so that it sits in that container.

4. Call appropriate methods to display the report on the screen. CALL METHOD <List/Grid/Tree>-><Method Name>

Example:

DATA : g_dock TYPE REF TO cl_gui_docking_container,

g_split TYPE REF TO cl_gui_easy_splitter_container,

g_cont1 TYPE REF TO cl_gui_container,

g_cont2 TYPE REF TO cl_gui_container,

g_grid1 TYPE REF TO cl_gui_alv_grid,

g_grid2 TYPE REF TO cl_gui_alv_grid.

i_mara is an internal table of structure MARA

SELECT * FROM mara INTO TABLE i_mara.

i_kna1 is an internal table of structure KNA1

SELECT * FROM kna1 INTO TABLE i_kna1.

To create an Object of type Docking Container

CREATE OBJECT g_dock

EXPORTING

side = cl_gui_docking_container=>dock_at_top

extension = 200 .

To Create an Object of Type Split Container. Here we can see that the Docking *Container Created above has been used as a parent .

CREATE OBJECT g_split

EXPORTING

parent = g_dock

orientation = 1 .

Easy Split container splits one Control into 2 manageable controls, each of them is used * to handle one GUI Container each

g_cont1 = g_split->top_left_container.

g_cont2 = g_split->bottom_right_container.

To Create an Object of type Grid . Here we can see that the Left Split Container * Created above has been used as a parent .

CREATE OBJECT g_grid1

EXPORTING

i_parent = g_cont1 .

To Create an Object of type Grid . Here we can see that the Right Split Container * Created above has been used as a parent .

CREATE OBJECT g_grid2

EXPORTING

i_parent = g_cont2 .

The method of Grid Control Object is used to display the Data.

CALL METHOD g_grid1->set_table_for_first_display

EXPORTING

i_structure_name = 'MARA'

CHANGING

it_outtab = i_mara[] .

The method of Grid Control Object is used to display the Data.

CALL METHOD g_grid2->set_table_for_first_display

EXPORTING

i_structure_name = 'KNA1'

CHANGING

it_outtab = i_kna1[] .

I hope it helps.

Hi,

The OO method is not used to print the LIST DISPLAY. If you go into the FM REUSE_ALV_LIST_DISPLAY you will not find any OO mehtods. It calls on another FM K_KKB_LIST_DISPLAY to generate and display the list. The OO method will always give you a Grid display.

Hope that Helps

Thanks
