Ax Configuration Files and SSRS

We had a new issue here.  One of our pre-production AOS needed to be rebuilt.  After our first deployment to the new environment, we found that SSRS reports were generating errors.  We were getting a pattern of 2 warnings, an error and 2 more warnings.


1) This warning was received twice:
Unable to get version information using existing WCF configuration from local storage.

Exception details:
Microsoft.Dynamics.AX.Framework.Services.Client.MetadataServiceException: Exception occurred on the metadata service on client or server. See exception details below:

2) The error was:
AXRDCE The AXRDCE extension caught an unexpected exception for report MWW_PYGByLocation.pdPYGByLocation.
The error message was:
Exception occurred on the metadata service on client or server. See exception details below:
>Unable to log on to Microsoft Dynamics AX.
   at Microsoft.Dynamics.AX.Framework.Services.Client.ServiceClientHelper.InvokeChannelOperation[TResult,TChannel](IServiceClient`1 client, Func`2 operationInvoker, Func`2 exceptionWrapper)

Then the warnings above repeated themselves twice.

Also, when I tried running any report from the SSRS server, I kept getting an error about not being able to set or retrieve the default value for parameter "CompanyName".

After researching the normal list of solutions, such as: restarting the AOS, clean the caches, doing a full CIL compile and refreshing the client side services; I decided to research the issue around the company name.  This finally led me to the following Tech Net article:  https://technet.microsoft.com/en-us/library/hh389774.aspx.

It turns out that the Business Connector information and authentication methods are not stored in SSRS reports as I had previously thought.  Rather, they are held in a designated configuration file (it must be named Microsoft.Dynamics.AX.ReportConfiguration.axc) that must be placed <SSRS Server path>\Reporting Services\ReportServer\bin directory.

After restarting SSRS, everything was working as norma.
