How to call ALV Report and SMARTFORMS through Pushbutton

Question

hi,
i have created a report.My task is to create two buttons:
1)ALV Report.
2)SMARTFROMS.
Through these button i have to call ALV Report and SMARTFORMS. i have created both button and when i execute the program,
it shows me the button but not working when i click on it.
this is the coding i have used in my report for calling ALV Report.
''Tables sscrfields,
DATA flag(1) Type c.
selection-screen: begin of screen 500 AS WINDOW TITLE tit,
BEGIN OF LINE,
PUSHBUTTON 2(18) but1 USER-COMMAND cli1,
end of line,
BEGIN OF LINE,
PUSHBUTTON 2(18) but2 USER-COMMAND cli2,
end of line,
end of screen 500.
SET PF-STATUS 'STATUS_0100'.
at selection-screen.
case sscrfields.
WHEN 'cli1'.
flag = '1'.
WHEN 'cli2'.
flag = '2'.
endcase.
at USER-COMMAND.
CASE SY-UCOMM.
WHEN 'Detail'.
select vbakkunnr VBakernam VBAkaudat vbakaufnr vbapKWMENG vbapmatnr vbap~ARKTX
into but1
from vbak inner join vbap
on vbakvbeln = vbapvbeln.
ENDSELECT.
ENDCASE.
START-OF-SELECTION.
tit = 'Format'.
but1 = 'ALV Report'.
but2 = 'SMARTFORMS'.
CALL SELECTION-SCREEN 500.
and i also use in my report
''case sscrfields-ucomm'' and ''submit my_report'' but the still button doesn't show the result.
Thanks & Regards,

Hi,
         I  understood your requirement. What i found is,  you are creating screen 500 and call it after START-OF-SELECTION,
at that time your AT USER-COMMAND doesn't work.
So what i would suggest , u should create GUI STATUS named ' PFSTAT' 
having one functional key 'EXIT'  that is standard u can just name it
and
other two u can assign in Freely assigned Function keys as 'BUT1' & 'BUT2'.  and than in Application Toolbar u jst have it in ITEM LIST by typing BUT1 and BUT2.
For 'BUT1'  text would be 'ALV'  and 'BUT2' text would be 'SMARTFORMS'.
Now in Program you can code,,,
START-OF-SELECTION.
SET PF-STATUS 'PFSTAT'.
WRITE:/ 'TEST'.
at user-command.
  case SY-UCOMM.
    WHEN 'BUT1'.
    WHEN 'BUT2'.
    WHEN 'EXIT'.
       LEAVE PROGRAM.
  endcase.
In Program u set PF STATUS and use at user-command event, whcih gets triggered when u click on button . When u execute program you get two button in application tooldbar.
Please do needful.
Thanks,
