Report 10.1.2.0.2 - DESFORMAT=spreadsheet - Report does not appear

Question

We use Report 10.1.2.0.2 - DESFORMAT=spreadsheet
RDF Report try to appear for 1 second and then disappear.
In the report there isn't image or particular object.
There is only one grid from db table.
The form coll the report with this procedure:
PROCEDURE RUN_REPORT_OBJECT_PROC
( rep_fileobj VARCHAR2,
rep_filename VARCHAR2,
rep_server VARCHAR2,
rep_desformat VARCHAR2,
rep_desname VARCHAR2,
rep_destype NUMBER,
rep_paramlist PARAMLIST ) IS
-- Local var
rep_id REPORT_OBJECT;
rep_message VARCHAR2(100);
rep_status VARCHAR2(100);
vjob_id VARCHAR2(100);
choice NUMBER ;
BEGIN
-- Estrae il report_id
rep_id := find_report_object(rep_fileobj);
-- Impostazione parametri RUNTIME del report
SET_REPORT_OBJECT_PROPERTY(rep_id,REPORT_SERVER,rep_server);
SET_REPORT_OBJECT_PROPERTY(rep_id,REPORT_DESFORMAT,rep_desformat);
SET_REPORT_OBJECT_PROPERTY(rep_id,REPORT_DESTYPE,rep_destype);
-- SET_REPORT_OBJECT_PROPERTY(rep_id,REPORT_DESNAME,rep_desname);
SET_REPORT_OBJECT_PROPERTY(rep_id,REPORT_FILENAME,rep_filename);
-- Lancia RUN_REPORT_OBJECT con o senza lista parametri
IF ( NOT Id_Null( rep_paramlist ) ) THEN
rep_message := run_report_object( rep_id, rep_paramlist );
ELSE
rep_message := run_report_object( rep_id );
END IF ;
-- Attesa processo asincrono di generazione del report termini
rep_status := 'RUNNING' ;
WHILE rep_status IN ('RUNNING','OPENING_REPORT','ENQUEUED') LOOP
rep_status := report_object_status( rep_message );
END LOOP ;
-- Estrazione JOB_ID
vjob_id := SUBSTR( rep_message, LENGTH( rep_server ) + 2, LENGTH( rep_message ) ) ;
-- Visualizzazione report sul WEB
IF rep_status = 'FINISHED' THEN
web.show_document( '/reports/rwservlet/getjobid' || vjob_id ||
'?server=' || rep_server, '_blank');
ELSE
message ( 'Creazione report fallita. Errore : ' || rep_status );
END IF;
END;
and the parameter passed to the procedure:
run_report_object_proc( 'MG_CAUSALI_MOV', :GLOBAL.rep_path_name||'\MG\mg_causali_mov_excel.RDF',
:GLOBAL.REP_SERVER_NAME, 'SPREADSHEET', '', CACHE, pl_id ) ;
The parameter :GLOBAL.... are correct: the PDF report run correctly.
Where is the problem ?????
The application server control show report SPREADSHEET terminated succesfully and
in the report cache the htm file are present and is correct for Excel (we opened the fil ewith excel).
Thanks in advance

Hi dmars,
report runs perfectly if I call it directly from Reports Server, from browser, using reports server URL.
When I call it from the form, it opens Excel file, but it's just empty.
As I understood, there is no way to call excel-compatible report wit run_report_object.
Also, what I learned after browsing internet,- to get nice and neat excel report one has to start with making excel layout first, save it as HTML, open this file in Reports as web report and manually update the code with java script lines.
So, as a matter of fact, SPREADSHEET format was sort of dead-end feature of Reports10G/9i.
