what is the difference between at selection screen event and at selection screen output.

Hi,

at selection screen------when user enters the values in the feilds of the selection screen and clicks on execution button,this event gets triggered.this event is basically for checking the value entered by the user for the feild of the selection screen i.e data validity checking.this event is for entire selection screen.

at selection screen output-----

This event is executed at PBO of the selection screen every time the user presses

ENTER - in contrast to INITIALIZATION . Therefore, this event is not suitable for setting selection screen default values.

Also, since AT SELECTION-SCREEN OUTPUT is first executed after the variant is imported (if a variant is used)

and after adopting any values specified under SUBMIT in the WITH clause, changing the report parameters

or the selection options in AT SELECTION-SCREEN OUTPUT would destroy the specified values.

Here, however, you can use LOOP AT SCREEN or MODIFY SCREEN to change the input/output attributes of selection screen fields.

Example

Output all fields of the SELECT-OPTION NAME highlighted:

SELECT-OPTIONS NAME FOR SY-REPID MODIF ID XYZ.

....

AT SELECTION-SCREEN OUTPUT.

LOOP AT SCREEN.

CHECK SCREEN-GROUP1 = 'XYZ'.

SCREEN-INTENSIFIED = '1'.

MODIFY SCREEN.

ENDLOOP.

The addition MODIF ID XYZ to the key word SELECT-OPTIONS

assigns all fields of the selection option NAME to a group you can read in the field SCREEN-GROUP1 .

At PBO of the selection screen, all these fields are then set to highlighted.

Hi,

AT SELECTION-SCREEN OUTPUT it will be triggered before appearing the screen

AT SELECTION-SCREEN it will be triggered after the selection screen appearance(after user interaction)

AT SELECTION SCREEN

AT SELECTION-SCREEN is processed when the user presses ENTER or chooses another function on

the selection screen.

AT SELECTION SCREEN OUTPUT

AT SELECTION-SCREEN OUTPUT is processed before the selection screen is displayed on the

screen. You can use this event to modify the selection screen dynamically.

Hi Frds

Selection screen event: This event only makes sense in reports, i.e. in programs set to type 1 in the attributes. Type 1 programs are started via a logical database and always have a selection screen where the user can specify the database selections.

The event is processed when the selection screen has been processed (at the end of PAI ).

If an error message ( MESSAGE Emnr ) is sent during the event, all fields on the selection screen become ready for input.

After further user input, AT SELECTION-SCREEN is executed again.

At selection screen output:The AT SELECTION-SCREEN OUTPUT ... events assigned to the parameters or selection options are executed in the sequence they are declared in the program, i.e. in the sequence they appear on the selection screen.

The events assigned to the radio button groups are executed according to the first parameter of the radio button group.

The events assigned to the blocks are executed "from the inside to the outside".

The event are triggered depended on the way the output is generated .

Initialization : triggered when the report is loaded in memory.

At selection-screen output : triggered when the selection screen is loaded in memory before being displayed.

At selection-screen / <field> : before leaving the selection screen.

start-of-selection : the first event for displaying the report.

end-of-selection : after the start-of-selection is completed.

classiscal report events.

top-of-page : every time a new page is started in the list.

end-of-page : every time the list data reaches the footer region of the page.

interactive report events.

top of page during line selection : top of page event for secondary list.

at line-selection : evey time user dbl-clicks(F2) on the list data.

at pF<key> : function key from F5 to F12 to perform interactive action on the list.

Initialization : triggered when the report is loaded in memory.

At selection-screen output : triggered when the selection screen is loaded in memory before being displayed.

Hi,

AT SELECTION-SCREEN

Syntax

AT SELECTION-SCREEN selscreen_event.

Effect

This statement defines event blocks for different events selscreen_event that are triggered by the ABAP runtime environment during selection screen processing.

Selection screen events occur immediately before sending a selection screen and after certain user actions on a displayed selection screen. They assist in selection screen processing in the ABAP program.

AT SELECTION-SCREEN is triggered at least twice during actions on selection screens that are linked into another selection screen as a subscreen - first for the linked selection screen itself, and then for the linking selection screens.

Note

The event blocks after AT SELECTION-SCREEN are implemented internally as procedures. Declarative statments in these event blocks create local data.

AT Selection-screen output:

Effect

This event is triggered at the screen event PBO of a selection screen. In the event block, the selection screen can be prepared through assignments to the data objects of parameters and selection criteria and through dynamic screen modifications.

Note

The assignments to input fields in the event block AT SELECTION-SCREEN OUTPUT always affect the selection screen and overwrite the user inputs from previous displays of the same selection screen. Assignments in the event blocks LOAD-OF-PROGRAM oder INITIALIZATION, on the other hand, only have an effect at first program start.

Renjith Michael.
