report id  report object;
reportserverjob varchar2(100);
report_status varchar2(20);
begin
report_id := find_report_object('myreport');
set_report_object_property(report_id,REPORT_FILENAME,'c:\developersuitehome_1\reports\'||p_repname||'.rep');
set_report_object_property(report_id,REPORT_EXECUTION_MODE,BATCH);
set_report_object_property(report_id,REPORT_COMM_MODE,ASYNCHRONOUS);
set_report_object_property(report_id,REPORT_DESTYPE,FILE);
set_report_object_property(report_id,REPORT_DESNAME,'c:\reports\'||p_repname||'.pdf');
set_report_object_property(report_id,REPORT_DESFORMAT,'pdf');
set_report_object_property(report_id,REPORT_SERVER,'rep_raysoft');
reportserverjob := run_report_object(report_id);
if rep_status = 'FINISHED' then
copy_report_object_output (reportserverjob,'c/'||prepname||'.pdf');
host('c/'||prepname||'.pdf',no_screen);
message('report '||p_repname||' completed successfully');
else
message('error when running '||p_repname||' report .');
end if;
end;

Dear All,
thanks for your attention
really i modify my code to be appear as follow
PROCEDURE OPEN_MY_REPORT (p_repname Varchar2) IS
v_report_id Report_Object;
vc_ReportServerJob VARCHAR2(100); /* unique id for each Report request */
vc_rep_status VARCHAR2(100); /* status of the Report job */
v_reportservername VARCHAR2(50):='rep_raysoft'; /* THE NAME OF THE REPORT SERVER*/
vjob_id VARCHAR2(100); /* job_id as number only string*/
BEGIN
/* Get a handle to the Report Object itself. */
v_report_id:= FIND_REPORT_OBJECT('MYREPORT');
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_FILENAME,'C:\DevSuiteHome_1\reports\'||p_repname||'.rep');
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_COMM_MODE,SYNCHRONOUS);
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_DESTYPE,FILE);
/* Define the report output format and the name of the Reports Server
as well as a parameter form to be displayedwhen required. */
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_DESFORMAT,'PDF');
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_SERVER,v_reportservername);
if p_repname = 'REPCENTERSPREADING' then
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_OTHER,'paramform=yes');
else
SET_REPORT_OBJECT_PROPERTY(v_report_id,REPORT_OTHER,'paramform=no');
end if ;
vc_ReportServerJob := RUN_REPORT_OBJECT(v_report_id);
message(vc_ReportServerJob);
message(vc_ReportServerJob);
vjob_id := substr(vc_ReportServerJob,length(v_reportservername)+2,length(vc_ReportServerJob));
message(vjob_id);
message(vjob_id);
/* If finished, check the report status . */
vc_rep_status := REPORT_OBJECT_STATUS(vc_ReportServerJob);
IF vc_rep_status='FINISHED' THEN
/* Call the Reports output to be displayed in a separate browser
window. The URL for relative addressing is valid only when the Reports
Server resides on the same host as the Forms Server. For accessing a
remote Reports, you must use the prefix http://hostname:port/ */
WEB.SHOW_DOCUMENT ('/reports/rwservlet/getjobid'|| vjob_id||'?server=rep_raysoft','_blank');
ELSE
message ('Report failed with error message '||vc_rep_status);
END IF;
END;
and it helps me to display the parameter form but i face another problem that is when i enter values for my parameter it gives me the following error
REP-52007: Parameter form format error.
note: i test the report directly from report builder and it work successfully without any problem
so can anyone help me please
