hi,

at selection screen event is used for validating the screen fields .

for ex when u wanna display text buttons based on selecting radio buttons in such caes we go for AT SELECTION-SCREEN EVENT

GENERALLY AT SELECTION-SCREEN EVENT is triggered before start-of-selection event.

for ex:

at selection-screen.

if screen-name = 'p1'.

screen-required = 1.

modify screen.

endif.

if screen-name = 'p2'.

screen-input = 0.

modify screen.

endif.

in the above ex p1 screen field is mandatory. system wont allow u 2 process further with out giving value to it.

p2 is disabled while selection screen display for user.

to have such conditions we go for at selection-screen event.

start-of-selection event is used for selecting data from database tables into user defined tables or to structures

for ex: Start-of-selection.

select * from mara into table itab where ................

start-of-selection event in reporting is the default event that will be triggered.

if helpful reward some points.

Hi,

Start-of-selection—

this is the first event for your list once all the events are triggered in selection screen the data is retirve from the database.

The REPORT statement always executes a START-OF-SELECTION implcitly. Consequently all processing logic between the REPORT statement and the next event keyword is automatically processed in the START-OF-SELECTION event.

Immediately afterwards, the system processes the statements that belong to an explicit START-OF-SELECTION block.

At-selection screen

AT SELECTION-SCREEN is used process the user commands

AT SELCTION-SCREEN OUPUT is used for the display/change mode of selection screen fields

***do rewards if usefull

<b>START-OF-SELECTION</b>

Event keywords for defining event blocks for reporting events.

Syntax

<u>START-OF-SELECTION.</u>

After the selection screen has been processed, the runtime environment triggers the LOAD-OF-PROGRAM event, and the corresponding event block is executed.

<u>AT SELECTION-SCREEN</u>

User actions on a selection screen or on a list trigger certain events in the ABAP runtime environment. This event key word helps to validate the parameters/select-options on the Selection screen.
