Answer / sivaramakrishna

hellow mr navven all above answeres were wrong.
at_selection_screen we use this event for multiple
selection scteen field validation. this is the default
event triguured automatically .

but at_user_command this event is triggured when ever the
end user makes an aciton by clicking menu options or
buttons on tool bar.

Answer / ravikanth

@Sivaramakrishna
I suggest ur answer is right one.

thanks to other posts as well.

Answer / kallol banerjee

Yes both can be maintained for same screen. But at user-
command will be triggered automatically and to work with at
line-selection implicitly we need to assign PICK to F2.
Then both will work fine.

Answer / venkateswarlu

Yes we can write the both the events in the same screen. At
Line-Selection is used the the current list stored into
sy-lsindex. When u double click on the list at user-command
will be triggered.

Answer / prabhakar reddy

as of my knowledge if we written boath and we define set-pf-status at line-selection will not trigger.
only at user-command will trigger.

if we commant set-pf-status then at-line-selection will trigger.
