Hi all, I've build a few reports in visual studio, they work and they don't work, in a minute I can run them next minute I can't and I get this errors in event viewer every time they can't be run: Report Server (MSSQLSERVER) cannot load the SQLPDW extension. Report Server (MSSQLSERVER) cannot load the TERADATA extension. Any idea qhat I need to do to avoid this? Thanks in advance

You can try disabling the extension section in the config file. TERADATA is a data extension in the config file.

I have found that resolution online, but on my Config file I don't have that extension.

Hi Nrodri, This error occurs because the Teradata extension is registered in the Reporting Services configuration file by default, but the Teradata assemblies are not shipped with SQL Server 2008 or as part of the .NET Framework. If the error message does not bother you, you can ignore the error when it is logged. However, if you want to avoid this error, do one of the following: Open the Reporting Services configuration file located in folder C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportServer, remove or comment out the Teradata extension. Do this only if you do not require functionality that the Teradata extension provides. Install the .NET Data Provider for Teradata. Do this only if you require functionality that the Teradata extension provides. You can obtain the provider from the Teradata Web site. Reporting Services requires that the provider be version 12 or later.
