Hi,

The event AT SELECTION-SCREEN is the basic form of a whole series of events that occur

while the selection screen is being processed.

The standard selection screen in an executable program or in the logical database linked to it is

automatically called between the INITIALIZATION and START-OF-SELECTION events. When

you call the selection screen, and when users interact with it, the ABAP runtime environment

generates selection screen events, which occur between INITIALIZATION and START-OFSELECTION.

You can define event blocks for these events in your program to change the selection screen or

process user input.

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.

AT SELECTION SCREEN OUTPUT 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.

AT SELECTION-SCREEN ON <field> is triggered when the contents of each individual input field are passed from the selection screen

to the ABAP program. The input field <field> can be checked in the corresponding event block.

If an error message occurs within this event block, the corresponding field is made ready for input

again on the selection screen.

It will helpful to u.

Thanks,

Shankar
