SSRS data driven subscription error

Question

I have a data driven subscription with 71 parameters. Every-time I run my subscription I get 5 errors and 71 of 71 processed with 5 errors. But when I count my report only 66 reports have been created. I tried to check the log but couldn't find any errors other than at Microsoft.ReportingServices.Diagnostics.RevertImpersonationContext.Run(ContextBody callback) at Microsoft.ReportingServices.Diagnostics.ExtensionClassFactory.CreateExtensionObject(Extension extConfig, Boolean typeOnly). library!ReportServer_0-43!3b10!11/10/2015-11:46:20:: i INFO: Call to GetSystemPropertiesAction(). library!ReportServer_0-43!411c!11/10/2015-11:46:20:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.LogonFailedException: Logon attempt for user 'user' failed., Microsoft.ReportingServices.Diagnostics.Utilities.LogonFailedException: Log on failed.

Thanks in advance!

To identify which logs are failing, you can view the report server's execution logs:

Use ReportServer
select * from ExecutionLog order by TimeStart DESC

The 'ReportID' field can be looked up in the reportserver's 'catalog' table. I find that having an SSRS report set up that queries this is invaluable.

Once you identify the reports that are failing (via the above queries) then you can try running them manually, to see if they work. If they do work, then set up a subscription for just those reports, and see if they work when run as a subscription.

If you've never had a problem with these before, my bet is that the datasources use pass-through authentication, which works when logged in, but not when run automatically.

Let us know how you get on!
