Answer 1

Hi Kiran,
  Yes, it is possible to use both at line selecion and at
  user command at a time.
AT LINE-SELECTION.
Event in interactive reporting
This event is processed whenever the user chooses a valid line in the list (i.e. a line generated by statements such as WRITE,ULINE, or SKIP) with the cursor and presses the function key which has the function PICK in the interface definition. This should normally be the function key F2, because it has the same effect as double-clicking the mouse, or clicking once in the case of a hotspot.
The processing for the event AT LINE-SELECTION usually generates further list output (the details list) which completely covers the current list display. If you want the current list display to remain visible (to aid user orientation), you can do this with the key word WINDOW.
AT USER-COMMAND.
Event in interactive reporting
This event is executed whenever the user presses a function key in the list or makes an entry in the command field.
DATA: NUMBER1 TYPE I VALUE 20,
      NUMBER2 TYPE I VALUE  5,
      RESULT  TYPE I.
START-OF-SELECTION.
  WRITE: / NUMBER1, '?', NUMBER2.
AT USER-COMMAND.
  CASE SY-UCOMM.
    WHEN 'ADD'.
      RESULT = NUMBER1 + NUMBER2.
    WHEN 'SUBT'.
      RESULT = NUMBER1 - NUMBER2.
    WHEN 'MULT'.
      RESULT = NUMBER1 * NUMBER2.
    WHEN 'DIVI'.
      RESULT = NUMBER1 / NUMBER2.
    WHEN OTHERS.
      WRITE 'Unknown function code'.
      EXIT.
  ENDCASE.
  WRITE: / 'Result:', RESULT.
After entry of a function code, the appropriate processing is performed under the event AT USER-COMMAND and the result is displayed in the details list.
