Answer 1

create or replace trigger deny_dec_pu before update of PU on ARTICLE
 for each row
 declare     
 erreur_pu exception;
  begin

     *insert into erreur values ('Operation de MAJ',sysdate);*

      -- this intruction is never executec why ?          

  if (:new.pu < :old.pu) then
  raise erreur_pu ; 
 end if;
 exception 
 when erreur_pu then 
  Raise_application_error(-20100, 'rrrrrrrr', FALSE); 

 end;
