ALV OOPS

1. Declare reference variables for the ALV Grid Control and the container. In addition, declare an internal table that you fill with selected data later on:

DATA: grid TYPE REF TO cl_gui_alv_grid,

g_custom_container TYPE REF TO cl_gui_custom_container

gt_sflight TYPE TABLE OF sflight.

In order to integrate a control into a screen, you can use four different container controls (in this example, we use the custom container control).

2. Create a standard screen and mark an area for the custom container control in the graphical Screen Painter (icon identified by letter 'C'). Assign name CCCONTAINER to this area.

Exercise 1: Reserving an Area for a Control of the Controls Tutorial explains how to mark an area in the alphanumerical Screen Painter version.

3. In the PBO module of the screen, you must now instantiate the container control and the ALV Grid Control. By doing this, you create a link between the container control and the screen, using the container created in the Screen Painter. Using parameter parent , you define the container control as the parent of the ALV Grid Control:

IF g_custom_container IS INITIAL.

CREATE OBJECT g_custom_container

EXPORTING

CONTAINER_NAME = 'CCCONTAINER'.

CREATE OBJECT GRID1

EXPORTING

I_PARENT = g_custom_container.

ENDIF.

The IF query of reference variable g_custom_container ensures that the instances are only generated when the PBO is processed for the first time.

Normally, you must use method cl_gui_cfw=>flush to pass the methods called to the frontend. However, since the Control Framework performs an automatic flush at the end of the PBO module, this step is not required here.

When you start the program, although the two instances (the container control and the ALV Grid Control) are generated, they are not visible.

Displaying a List in the ALV Grid Control

Once you have created the ALV Grid Control and integrated it into a screen using a container control, you must pass the data and its structure to the ALV Grid Control:

1. Fill the internal table with data:

SELECT * FROM sflight INTO TABLE gt_sflight.

2. Pass the output table and the structure data to the ALV Grid Control. Again, ensure to call this method only once after the ALV Grid Control is created:

CALL METHOD grid->set_table_for_first_display

EXPORTING I_STRUCTURE_NAME = 'SFLIGHT'

CHANGING IT_OUTTAB = gt_sflight.

In this case, the structure data is provided through the Data Dictionary. The ALV Grid Control gets the field information from table SFLIGHT and displays all fiel

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

Hope this helps u..
