hi

good

Search the ABAP Objects forum for my sample reports (beginning with ZUS_SDN). All of them contain at least one example of OO-based event handling. These are simplified reports showing the only the crucial points of event handling.

STEPS:

1. Call a screen.

2. Go to the screen layout and add a custom control .

3. Go to attribute and give a name to the custom control (Ex: 'CUSTOM_CONTROL').

4. Give a name to the ok_code ( Ex: ok_code) in the attribute of the screen.

5. Data Declaration section:

I. Data declaration for ALV

a. Declare a object type cl_gui_alv_grid for ALV Grid instance referance

b. Declare a object type cl_gui_custom_container for Custom container instance referance

c. Declare Name of the custom control added to the screen

d. Declare field catalog table of type lvc_t_fcat.

e. Declare layout of type lvc_s_layo.

II. Data declaration for fetching data as input

III. Declare variables for ok_code.

6. Set pf-status and titlebar for the screen.

7. Write PBO. IN PBO do the following:

i. Check whether gr_alvgrid is initial.

a. If yes do the following.

• Create instance for custom container (gr_container) by passing the container name.

• Create instance for ALV grid by passing the custom control instance reference.

• select the material data from database

• Build field ctalog

• Build layout

• Call method ‘set_table_for_first_display’ for the object gr_alvgrid(alv grid instance reference) with passing layout, input table and field catalog.

b. If NO do the following.

• Call method ‘refresh_table_display for the object gr_alvgrid(alv grid instance reference).

ii.

8. Write PAI. IN PAI do the following:

Check the ok_code, if ‘Exit’ then leave from program.

All the user commands where user do any actions in the screen will be code here . For this purpose check the value of ok_code and according that ok_code, code the functionality for the particular user actions.
