Increasing the Time-Out Values for Microsoft SQL Server Reporting Services

Consider increasing the following SSRS configuration parameter values so that the large reports can be opened successfully.

Report Execution Time-out

A report execution time-out value is the maximum number of seconds that report processing can continue before it is stopped. This value is defined at the system level. You can vary this setting for individual reports.


For example, you can run a report that has underlying queries that cannot be completed within the time-out period. The following error will be shown on the Report Manager like this:

An error has occurred during report processing. (rsProcessingAborted)
Query execution failed for dataset 'DataSet1'. (rsErrorExecutingCommand)
A severe error occurred on the current command. The results, if any, should be discarded. Operation cancelled by user.


Increase the Report execution time-out value. For details, see

HTTP Runtime Execution Timeout


You cannot open the report and you get the following error instead. This error generally occurs when the HTTP runtime execution timeout is too short.

The remote server returned an error: (500) Internal Server Error.


  1. Open the Report Server’s Web.config file, which is usually in this location:

    <Drive>:\Program Files\Microsoft SQL Server\MSRS<version number>.<instance name>\Reporting Services\ReportServer
  2. Locate the HttpRuntime parameter and alter the value. If it doesn't exist, you will have to create it within the section.

    The default value is 9000, and the value is in the seconds. The maximum value is 922337203685.

  3. Increase the executionTimeout value to allow the report to be rendered.
