If you are using a report program, you don't have to call the screen unless after the first selection screen is being processed that you want to call another screen.

Then it would be dependent on your requirements whether it would go in the AT SELECTION SCREEN or in your START-OF-SELECTION processing.

If u declared any parameters or select-options , this automatically triggers selection screen and always selection screen default number is 1000 ,

and if u want to call different screen from a report then

we can use call screen 'XYZ'.

XYZ is a number other than 1000 ,

and this code is written in start-of-selection .

If u want to change any value on selection screen then the coding is to be written in

INITIALIZATION .

Hi Venkatesh..

In classical reports, the order of events is as follows

1. Initialization

2. At selection screen

3. Start of selection.

4. Top-of-page

5. End-of-selection.

6. End-of-page.

Initialization event is for providing default initial values for the fields of sel-screen.

It'll trigger after the User executes the program and before load-program.

At selection-screen is to provide field validations on selection screen.

It'll trigger at PBO of the selection screen

Start-of-selection is the default driver event. But if u mention initialization event in ur program, then u must specify start-of-selection event.

It'll trigger after user give the input values in sel-screen.

If this works out for u, reward me points plz

Thanks

Hi,

before coding Initializatio event triggers first after that start-of-selection event triggers after these two events at-selection screen event triggers.

for better understanding just write simple abap program by using these 3 events after that use debug the code.

Thanks
