SharePoint 2013 - SSRS Removing unused Teradata and SQLPDW extensions

By default Reporting Services includes references to TeraData and PQLPDW extensions that are not included in the install. This will generate “Unexpected” level errors in the SharePoint ULS logs. While these errors don’t hurt anything, they do create a lot of noise in the log files. These errors can be resolved by removing these references from the Reporting Services configuration. 

1.       Open PowerShell on the App server

2.       Create the below PowerShell Scripts

3.       Run the following scripts in your PowerShell window:

a.       Remove_TeraData_Extension_From_SSRS.ps1

b.      Remove_SQLPDW_Extension_From_SSRS.ps1

Remove_TeraData_Extension_From_SSRS.ps1:
