ATselection screen output - You can make the dynamic change in selection screen at runtime

ATselection screen field , ATselection screen on value , ATselection screen on - All are same

we rite like AT SELECTION SCREEN ON s_bukrs

This we will use for validation of that select option or parameter if user enters the value.

Rewards if useful.

Hi ,

AT selection screen output -- get triggerreds before displaying the selection-screen.

At selection screen field -- gets triggered when the any input is given to the field.

AT seclection screen on value -- its acts like a f4 function on that field.

At selection screen on help -- its acts like f1 function on that field.

regards,

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.

At-Selection screen

This is PAI--Process after Input...
