Example
This program works with a self-defined GUI status MYLIST. The function associated there with the function code MY_SELECTION triggers the event AT USER-COMMAND when the list is displayed and also creates details lists.
REPORT demo_at_user_command.
START-OF-SELECTION.
SET PF-STATUS 'MYLIST'.
WRITE 'List line'.
AT USER-COMMAND.
IF sy-lsind = 20.
SET PF-STATUS 'MYLIST' EXCLUDING 'MY_SELECTION'.
ENDIF.
CASE sy-ucomm.
WHEN 'MY_SELECTION'.
WRITE: / 'You worked on list', sy-listi,
/ 'You are on list', sy-lsind.
...
ENDCASE.
