Deploying Custom Data Extension to Sharepoint 2010 with SSRS in integrated mode

Hi All!

We created an SSRS Data Extension that works perfect wtih SSRS 2008/2012 and it's no problem to deploy the reports and even use the Report in Sharepoint.

But the data extension is not recognized anymore, when SSRS runs in Sharepointintegrated mode. The report comes up with an error message, that the extension is unkown.

I found out, that SSRS in integrated mode doesn't have a regular rsreportserver.config file anymore. I found a different rsreportserver.config in the "Common Files" directory but it looks completely different so I wasn't able to apply the regular installations steps as shown in this article:

So my question is: Can anyone point me to a step by step guide about how to deploy a custom extension to SSRS in Sharepoint Integrated Mode?

Thanks in advance for your help.

Kind regards,

Patrick
