I had an issue trying to find what was causing a data-driven report subscription error.  The SSRS report is deployed to SharePoint, and Reporting Services is in SharePoint Integrated mode. The subscription was showing last results as “Done: 15 processed of 15 total; 7 errors.” It took awhile to find the pieces I needed to figure out what was causing the error.

I found some information about looking at Report History in SharePoint and creating a New Snapshot, which would give me the last known error.  However, since some of the reports had run successfully this did not work. 

Next I tried looking at the Report Server database in the ExecutionLog tables.  I isolated the query results to just the one report subscription by writing a query like this:

Use ReportServer
select * from ExecutionLog3
where  RequestType = ‘Subscription’ AND timeStart >’2012-05-29 11:30:00.000′
ORDER BY TimeStart DESC

This only returned the successes, not the failures.

Finally, I tried looking in the Report Server Trace Log file.  There was very little in the log file and nothing to do with my subscription.  I knew that the Trace Log file should hold the information I needed.  After much poking around I realized that I had made a fundamental error in my assumption about the architecture. The Trace Log file resides on the SharePoint server, not the Report Services database server. 

Find the Trace Log

The Trace log files can be found on the SharePoint server, usually here:  C:Microsoft SQL ServerMSRS10_50.MSSQLSERVERReporting ServicesLogFiles

Find the ScheduleID for your Subscription

Find the Schedule ID of the most recent subscription by querying the ReportServer database:

select
‘SubnDesc’ = s.Description,
‘SubnOwner’ = us.UserName,
‘LastStatus’ = s.LastStatus,
‘LastRun’ = s.LastRunTime,
‘ReportPath’ = c.Path,
‘ReportModifiedBy’ = uc.UserName,
‘ScheduleId’ = rs.ScheduleId,
‘SubscriptionId’ = s.SubscriptionID
from ReportServer.dbo.Subscriptions s
join ReportServer.dbo.Catalog c on c.ItemID = s.Report_OID
join ReportServer.dbo.ReportSchedule rs on rs.SubscriptionID = s.SubscriptionID
join ReportServer.dbo.Users uc on uc.UserID = c.ModifiedByID
join ReportServer.dbo.Users us on us.UserID = s.OwnerId

Search for the ScheduleID in your Trace Log and find the Error message

Open the appropriate log file based on the time stamp being the most recent after the subscription ran, and search for the ScheduleID.  Once you find the first entry for your ScheduleID, look for anything that starts with e ERROR

The error message can look like this:

library!WindowsService_113!308!05/29/2012-10:31:17:: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.InvalidReportParameterException: , Microsoft.ReportingServices.Diagnostics.Utilities.InvalidReportParameterException: Default value or value provided for the report parameter ‘Manager’ is not a valid value.;

  5 Responses to “Finding Report Subscription Errors”

  1. I’ve got a subsription that i set up in Sharepoint and I too have results similar to yours:
    Done: 10 processed of 10 total; 10 errors.
    I cannot however find any errors in the log file
    I’m wondering if:
    1. I’m on the right server
    2. right SSRS instance, DB or whatever
    3. the error happened even before it hit the SSRS side
    I’m lost as to where and what these errors are
    Needless to say I also have no resulting report files in the folder as specified
    Any clues?

  2. do you have any idea on how to report users automatically if the subscription fails to run. In our environment we have around 150 reports running daily and we cannot check every report daily whether it got processed or failed. So I am wondering if you have any idea on how to report users automatically through emails if the subscription fails to run.

    I would really appreciate your help

    Thanks in advance
