Filtering data in historic report instances

Question

My goal is to filter data in a managed report instance without refreshing it.  But I am having issues even viewing an instance.  I am using Crystal Reports 2008 Server and the RAS API.  Code below displays reports fine (i.e. SI_INSTANCE=0) but not report instances (i.e. SI_INSTANCE=1).
Approach 1, Use reportSource from PSReportFactory:
//Here is my query:
String reportQuery = "SELECT * FROM CI_INFOOBJECTS " + "WHERE SI_NAME = '" + report.getName() +
              "' AND SI_KIND = '" + CeKind.CRYSTAL_REPORT + "' AND SI_INSTANCE = 1";
// Here I grab the latest report instance
IInfoObjects reports = iStore.query(reportQuery);
IInfoObject oInfoObject = (IInfoObject) reports.get(0);
IReportSourceFactory factoryPS = (IReportSourceFactory)es.getService("PSReportFactory");
Object reportSource = factoryPS.openReportSource((oInfoObject), getLocale());
// Here I prep and attempt to display
viewer.setReportSource( reportSource );
viewer.setDatabaseLogonInfos( newDBConnectionInfos() );
viewer.setEnableLogonPrompt( false );
viewer.setBestFitPage(true);
viewer.setOwnPage(false);
viewer.processHttpRequest();
processHttpRequest above throws:
com.crystaldecisions.sdk.occa.report.lib.ReportSDKException: Invalid job number.---- Error code:-2147215357 Error code name:internal
Approach 2, use ReportClientDocument from RASReportFactory...
// Same query as above:
String reportQuery = "SELECT * FROM CI_INFOOBJECTS " + "WHERE SI_NAME = '" + report.getName() +
              "' AND SI_KIND = '" + CeKind.CRYSTAL_REPORT + "' AND SI_INSTANCE = 1";
// Here I grab the latest report instance
IInfoObjects reports = iStore.query(reportQuery);
IInfoObject oInfoObject = (IInfoObject) reports.get(0);
IReportAppFactory raf = (IReportAppFactory)es.getService("RASReportFactory");
ReportClientDocument rcd = raf.openDocument(oInfoObject, OpenReportOptions._openAsReadOnly, getLocale());
// Here I prep and attempt to display
viewer.setReportSource(rcd.getReportSource());
This approach throws an exception from
raf.openDocument()
with error:
Cannot open report document. --- Item SI_NEWOBJECT was not found in the collection.
Of these approaches I prefer the second as I can potentially filter the data. 
Any ideas or help greatly appreciated as I am new to crystal reports.

Answer 1

Good call Ted, and thanks for the reply!  I had a bunch of Failed instances and it was choking on a failed one. 
Now that I have identified a successful instance, I'm having trouble displaying the historical report data. 
When I attempt to display using the PSReportFactory, from first approach above, it displays the report but I
don't get historic data, i.e. it is refreshing from the database.  Of course historic data display works in the
CMC so I'm sure it must be possible.  How can I get the viewer to show the data as it was when the report
was run?
Also, using the preferred RASReportFactory, from second approach, I get the following exception:
ReportSDKServerException: Failed to retrieve initial report values. For example, the database information for this report could be incomplete or
incorrect. This is a configuration problem. Please contact your system administrator.---- Error code:-2147467259 Error code name:failed
This seems odd as I am passing the database logon infos to the viewer, and it works the other way:
viewer.setDatabaseLogonInfos( newDBConnectionInfos() );
viewer.setEnableLogonPrompt( false );
Any ideas about how I can get it to work this way?
Thanks,
--Jeff.
