AT SELECTION-SCREEN

This event is processed before leaving the Selection Screen i.e. when the selection screen has been processed (at the end of PAI once the ABAP runtime environment has passed all the input data from selection screen to the ABAP program).

This event is used to validate the input provided through selection screen. If an error message occurs in this processing block, the selection screen is redisplayed with all of its fields ready for input. This allows you to check input values for consistency.

with this link you will get complete idea about the at selection screen events
