Dynamics AX2012 supports the ability to install multiple instances of reporting services on the same computer, which is great for Development and Testing environments. The steps are outlined here on TechNet (http://technet.microsoft.com/en-us/library/hh389760.aspx).
When running a report for the first time in AX after you have restarted the SSRS instance you receive the error,
“The DefaultValue expression for the report
parameter ‘AX_CompanyName’ contains an error: Request for the permission of type
‘System.Security.Permissions.EnvironmentPermission, mscorlib, Version=2.0.0.0,
Culture=neutral, PublicKeyToken=b77a5c561934e089′ failed.
(rsRuntimeErrorInExpression)”.

(rsRuntimeErrorInExpression)”.

Once the report is run again, it runs without error. To get by the error, you will need to edit the RsSrvPolicy.config file located in the ReportServer folder of the installed instance…setting the PermissionSetName=”FullTrust” as shown below.(https://community.dynamics.com/product/ax/axtechnical/b/axsupport/archive/2012/02/02/microsoft-dynamics-ax-2012-reporting-extensions-error-system-security-permissions-environmentpermission-while-running-report.aspx)
