Reports 10g problem: Before parameter form trigger(BPFT) problem

Question

In report bilder there is no problem - I get parameter form wit all the parameters, I initialized in BPFT
function BeforePForm return boolean is
s_date date;
begin
s_date := Trunc(SYSDATE);
if :PAR_TEM_OD is null then
     :PAR_TEM_OD := '1';
end if;     
if :PAR_TEM_DO is null then
     :PAR_TEM_DO := '9';
end if;     
if :PAR_DAT_OD is null then
     :PAR_DAT_OD := s_date ;
end if;     
if :PAR_DAT_Do is null then
     :PAR_DAT_Do := s_date ;
end if;     
return (TRUE);
end;
PAR_DAT_... is data type DATE wit input mask DD.MM.YYYY.
REPORT crashes when I run it from forms - no parameter form is displayed. When I initialize only CHAR PARAMETERS IN BPFT then I get result - parameter form is displayed. . The problem is when I want to initailize DATE parameters.
Any idea?

Why are you using srw.do_sql here? You are just performing some sql and pl/sql statements here. This is an explanation of do_sql in the Report Builder Help:
"Since you cannot perform *DDL statements* in PL/SQL, the SRW.DO_SQL packaged procedure is especially useful for performing them within Report Builder, instead of via a user exit."
So, your code would simply be:
function BeforePForm return boolean is
  segment2 varchar2(10);
begin
  select segment1
  into segment2
  from xxmssl_po_headers_all
  where rownum<2;
... etc. ...
end;
