Ok, for the release 2 its quite straightfoward, in your calling form you would have something like this code:
declare
     pl_id ParamList;
repid REPORT_OBJECT;
v_rep VARCHAR2(100);
v_rep_status VARCHAR2(20);
v_repsrv     VARCHAR2(100):= 'yourreportserver';
v_serv varchar2(50) := 'yourservername' ;
begin
pl_id := Get_Parameter_List('tmpdata');
if not id_null(pl_id) then
Destroy_Parameter_List( pl_id );
end if;
pl_id := Create_Parameter_List('tmpdata');
Add_Parameter(pl_id,'DESTYPE' ,TEXT_PARAMETER,'Screen' );
Add_Parameter(pl_id,'PARAMFORM' ,TEXT_PARAMETER,'NO' );
repid := FIND_REPORT_OBJECT('yourreport');     SET_REPORT_OBJECT_PROPERTY(repid,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_EXECUTION_MODE,RUNTIME);
SET_REPORT_OBJECT_PROPERTY(repid,REPORT_SERVER, v_repsrv);
set_report_object_property(repid,REPORT_DESTYPE,CACHE );
set_report_object_property(repid,REPORT_DESFORMAT,'SPREADSHEET' );
v_rep := RUN_REPORT_OBJECT(repid,pl_id);
v_rep := substr(v_rep,length(v_repsrv)+2,10 ) ;
end;
I have plenty of reports being formated to excel with this same method so it should work for you, the only diference with my previous code is this line.
set_report_object_property(repid,REPORT_DESFORMAT,'SPREADSHEET' );
The rest remains untouched.
Hope it helps.
