If you're using GP 2013 and SSRS there is a great Business Analyzer App that you can use on Windows 8 (x86/x64/ARM) devices.  By the time you are reading this blog there will have been a newly updated release of this app.  If you've previously been using the Business Analyzer app and install the latest update you will have to reselect your reports.

I encourage you to download this app and check it out!

I don’t want to get into the details of using it or setting it up, you can go to the following site for that information:

I do want to discuss a few points about the use of this application as it pertains to the support team and our partners.  The biggest pain point I think we’ll see for partners who want to demo this is that you cannot run the Business Analyzer app and the instance of SSRS that you are connecting to on the same machine.  So if you are planning to take your laptop to a customer site and demo Business Analyzer you may be limited by this.  This is a security issue with Windows 8 and not something we can work around.

You can however set this up on a single machine in a domain environment by using Hyper-V.  I currently have this solution up and running on my laptop and it is working fine.  Windows 8 comes with Hyper-V built in to it which is a huge plus.  So you will have the Business Analyzer application running natively on Windows 8, but you will be connecting to a Hyper-V instance on the same machine which is running SSRS.

If you’re not familiar with using Hyper-V on Windows 8 please look at the documentation found here: http://www.microsoft.com/en-us/download/details.aspx?id=36188 

One of the new features in the latest release is the ability to connect to SSRS while you're "Off Domain".  In the settings you will now be required to put in your credentials to connect to the SSRS server.  This will allow the app to pass your credentials for authentication even when your machine is not "On the Domain".  You do need to have an internet connection for this to work as it actually stores your password in the Windows Store vault, not local to the machine.

The last thing I will remind you of if you are running into problems getting this to connect to your SQL server is to open port 1433 on your firewall.  :-)
