Prevent User close or Cancel Sales Order manualy

Question

Hi all!
I am using SP Notification  to prevent user close or cancel Sales Order manually from pop up Menu.
Here is my SP>
If @object_type = '17' and (@transaction_type ='U')
BEGIN
if exists
  (SELECT T0.[DocNum] FROM ORDR T0 INNER JOIN RDR1 T1 ON T0.DocEntry = T1.DocEntry
WHERE T0.[CANCELED] ='Y' or  T0.[DocStatus] ='C' and T1.[TargetType] ='-1')
begin
set @error =100
set @error_message = N' Cannot Close directly !!! !'
end
End
But i not success because i think "U" and "A" event is not effect for this case.

Dear Tien,
Same thing you can do by user authorization.
Path:
Admin > system initialization >authorization >general authorization >cleck on Select user > General > Drag and Relate >Set flag for the cancel document and close document.
May this help you.
