ABAP AT LIST EVENT Statement syntax, information and example SAP source code

AT list_event

ABAP Syntax AT LINE-SELECTION

| USER-COMMAND
| PFnn .

What does it do? Defines event blocks for interactive list processing. The associated events occur if the screen cursor is positioned on a line in a displayed list and the user chooses an appropriate function. Each interactive list event increases the system field sy-lsind by one.
If the cursor is positioned on a line in a list displayed on the screen in an interactive list event, all the values stored using HIDE and belonging to the line in question are assigned the respective variables and the following system fields are filled with data:
System Field Meaning
sy-cpage Page number of the first displayed page of the list from which the event was triggered
sy-cucol Position of the column in the window from which the event was triggered (counting starts with 2)
sy-curow Position of the line in the window from which the event was triggered (counting starts with 1)
sy-lilli Number of the line from which the event was triggered
sy-lisel Content of the line that triggered the event (is limited to the first 255 characters)
sy-listi Index of the list from which the event was triggered
sy-lsind Index of the list level that was created in the event block
sy-staco Number of the first column displayed in the list from which the event was triggered (counting starts with 1)
sy-staro Number of the first line of the first page displayed of the list from which the event was triggered (counting starts with 1)
sy-ucomm Function code to which the user action that triggered the event is assigned

After each list event AT LINE-SELECTION , AT PFnn , and AT USER-COMMAND , the statement
NEW-PAGE PRINT OFF is executed explicity.

Latest notes: The list event AT PFnn is obsolete and the other two list events (preferably AT USER-COMMAND ) should be used instead.
