Ending Oracle rdf report in warning

Hi,

please let us know how to end  Oracle Rdf report in warning status based on some condition.

We tried below thing but it is not working

function AfterReport return boolean is
l_status boolean;
begin
srw.MESSAGE(112,'AfterReport- Before condition');
if :CS_1 > '0'
then
srw.MESSAGE(112,'AfterReport- within condition');
   l_status:=fnd_concurrent.set_completion_status('WARNING','WARNING: The CZK rate is not available');
   srw.MESSAGE(112,'AfterReport- warning status set');
   COMMIT;
   end if;
  return (l_status);
end;

Thanks,
Prasanna
