ABAP AT LINE-SELECTION Statement syntax, information and example SAP source code

AT LINE-SELECTION

Short Reference

ABAP Syntax AT LINE-SELECTION.

What does it do? This statement defines an event block whose event is triggered by the ABAP runtime environment when a screen list is displayed. This is provided the screen cursor is on a list line and you select a function using the function code PICK . By defining this event block, the standard list status is enhanced automatically in such a way that the function code F2 and, with it, the double-click mouse function is associated with the function code
PICK .

Latest notes: If the function key F2 is associated with a function code other than PICK , each double click triggers its event, usually AT USER-COMMAND , and not AT LINE-SELECTION .

Example ABAP Coding This program works with the standard list status. Selecting a line with the left mouse key triggers the event AT LINE-SELECTION and creates details lists.
