Disable SharePoint Service Application's Custom Errors and Enable Service Debug

You may have encountered the following error in SharePoint applications. You need to enable service debug to see real exception in the application.

If you are in a multi farm environment, first you need to find out where your service applications are running. For an example, assume that you need to know where reporting service is running.

Go to central administration and then go to Services on this server. Here you can change the Farm machine and can see whether reporting server instance is running. So note down machines which has reporting sever instance running.

Then log in to those machines and find reporting service web service application in IIS.

For that, you can change the View to Content View and select each SharePoint Web service and see whether ReportingWebService.svc is available. If yes, it the web application corresponding to reporting service service application.

Then open the web.config and add includeExceptionDetailInFaults=”true” to enable service debug.

<serviceBehaviors>     
    <behavior>
        <serviceDebug includeExceptionDetailInFaults="false" />
    </behavior>
    <behavior name="RSExecutionBehavior">
          <serviceThrottling maxConcurrentCalls="512" maxConcurrentInstances="512" />
    </behavior>
</serviceBehaviors>

Note: If service is running on multiple machines, you need to change all related web.config.
