I try to run report with parameters from my form.
In my report i define four user parameter:
acc - number(25)
cur - char(3)
date1 - data ('DD.MM.RR')
date2 - data ('DD.MM.RR')
Trigger "when-mouse-click" PushButton in my form:

declare
    repid REPORT_OBJECT;
    v_rep  VARCHAR2(100);
    rep_status varchar2(20);
  pl_id1 ParamList;    
  cr varchar2(3);
  acc varchar2(20);
  
BEGIN
  pl_id1 := Get_Parameter_List('vpv_list');
  IF NOT Id_Null(pl_id1) THEN
    Destroy_Parameter_List(pl_id1);
  END IF;
  go_block('PCR');  
  if substr(:pcr.ipcracc,6,3)=810 then
       cr:='RUR';
  else
       cr:='USD';
  end if;     
  pl_id1 := Create_Parameter_List('vpv_ex12');  
  acc:=:pcr.ipcracc;
  Add_Parameter(pl_id1, 'ACC',TEXT_PARAMETER, acc);
  Add_Parameter(pl_id1, 'CURR', TEXT_PARAMETER, cr);
  Add_Parameter(pl_id1, 'DATE1', DATA_PARAMETER, to_date(:pcr.dpcrsdt,'DD.MM.RR'));
  Add_Parameter(pl_id1, 'DATE2', DATA_PARAMETER, to_date(:pcr.dpcrfdt,'DD.MM.RR'));  
  
  Run_Product(REPORTS, 'vyp_par', SYNCHRONOUS, RUNTIME, FILESYSTEM, pl_id1, NULL);  
END;

but i get error: FRM-47012 Cannot add parameter DATE1 to Parameter List. Group 01-DEC-03 does not exist.

What i make wrong?

DATA_PARAMETER should hold recordgroup name and is used for passing ARRAYS of data between applications. If you need to pass DATE or any other scalar parameters, you should pass it as TEXT_PARAMETER.

I correct this..but now reports not response..
Reports background engine type that unable open 'vyp_par.rep Error while opening or saving a document.
What is this?
if i run this report without parameters
    repid := find_report_object('VYP');
    v_rep := RUN_REPORT_OBJECT(repid);
all ok.
?????
P.S. i  have rights only on SELECT in oracle schema.

What is in report log? I think that vyp_par.rep is not within REPORTSxx_PATH. You may also check real file name in report object definition. BTW, Run_Product works only with client/server deployment. What version/deployment do you use?

thank's, Sem.
it need write full path to report's file....

Don't do it, because you can not distribute your application: it wouldn't work on another directory structure. Set  REPORTSxx_PATH environment (registry) variable, where xx stands for reports version(25, 30, 60 or empty for 9i) to includ directory where your report is located.
