Hello Suresh,

Initialization event can be used for exactly what its name suggests, that is to initialise. All variables, tables that u may be using in ur report can be initialised (cleared and refreshed) here.

AT SELECTION SCREEN OUTPUT - The event is triggered just before the selection screen is shown. The event can be used to code for changing the seelction screen dynamically, according to the seelctions of the user.

Hope this helps.

Regards,

Johnson

Initialization is to initialize the values which will be executed before all the other events.

at selection screen output is like PBO mainly used for modifying the screen.

for use of at sel. scr. o/p go through the below programs

Screen Modifications -- demo_dynpro_modify_simple

Hi suresh,

1. Initialization = event is fired ONLY ONCE when program starts.

2. At selection-scren output :

Event is fired whenever screen is displayed,

ie. a) When we press ENTER key

b) when we select radiobutton / checkbox having user command

c) any other user command fired on screen

regards,

hi,

Initialization is used to intialise filed values before executing the report. where as at selection-screen output is used for validations of section screen fileds.

INITIALIZATION.

Processing event.

Executed before the selection screen is displayed.

The parameters (PARAMETERS ) and selection criteria (SELECT-OPTIONS ) defined in the program already contain default values (if specified). You can assign different values here and also change the database-specific selections.

Example

Define the last day of the previous month as the key date:

PARAMETERS QUAL_DAY TYPE D DEFAULT SY-DATUM.

INITIALIZATION.

QUAL_DAY+6(2) = '01'.

QUAL_DAY = QUAL_DAY - 1.

Here, the default value of QUAL_DAY is the current date, e.g. 05.04.88 ( QUAL_DAY = '19880405'). Two subseqent statements set the date first to the beginning of the month, e.g. 01.04.88 ( QUAL_DAY = '19880401') and then, by subtracting one day, to the last day of the previous month, e.g. 31.03.88 ( QUAL_DAY = '19880331').

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,

Initialization : where we will give initialization of all variables tables etc.

Selection-screen output.: gives the new output screen for given input values

<b>INITIALIZATION</b>

This event occurs before the standard selection screen is called. You can use it, for example, to initialize the input fields of the standard selection screen. This is the only possible way to change the default values of parameters or selection criteria defined in logical databases.

<b>AT SELECTION-SCREEN OUTPUT</b>

In the PBO of the selection screen, this event is triggered. This event block allows you to modify the selection screen directly before it is displayed.

Raman
