difference between at line selection and at user command

[former_member673464]

hi,

AT LINE-SELECTION.

<statements>.

As described in the section Dialog Status for Lists, the function code PICK is always added to the standard list status when you have an AT LINE-SELECTION event in your program.

If you assign PICK to other function keys or menu entries, AT LINE-SELECTION is also triggered when the user chooses then. You should avoid this for the sake of the semantics.

Conversely, if you have a more extensive program that does not react to line selection, you should not use the function code PICK. Instead you should assign a different function code to F2 , to ensure that as many events as possible trigger the AT USER-COMMAND event.

Event Block for User-Defined Function Codes

If the user chooses a function code during list processing that is neither processed by the system, or PICK or PF<nn>, the system triggers the event AT USER-COMMAND. For this event, you must define your own GUI status for a list. To react to your own function codes in a program, you must define the following event block:

AT USER-COMMAND.

<statements>.

In this event block, you can use an IF or CASE structure to tell the function codes apart. They are available in the system field SY-UCOMM. There are further system fields that are filled in list events, such as SY-LSIND and SY-PFKEY, that allow you to make further case distinctions.

Hi Ali,

Both events are used in Classical ALV Report.

AT USER COMMAND event will call when the user click the toolbar button.

AT LINE SELECTION - This event will call when the user select the particular record.
