Bussines connector and ssrs reports - internal AX querys not work

Hello, I work installing client - server implementation of microsoft dynamics AX 2009 and I have a little(big) problem:

Native ssrs reports not work. I edited CustSRS report and conclude that the error is in internal AX query.

VS Error:

Error 1 Unable to create object CustomerTransaction.AutoDesign [Preview] 0 0 

Event Log Warn:

Dynamics Adapter CreateAxaptaObject failed.

Unable to create object

Microsoft.Dynamics.BusinessConnectorNet.XppException

at Microsoft.Dynamics.BusinessConnectorNet.Axapta.CreateAxaptaObject(String className, Object param1)

at Microsoft.Dynamics.Framework.BusinessConnector.Session.DynamicsAdapter.CreateAxaptaObject(String className, Object param1)

another:

Microsoft Dynamics AX Business Connector Session 9.

Se produjo una excepción X++.

Unable to create object

My AX impl:

1 server with AOS, Enterprise Portal, Roll Center, IIF, Share Point Services

1 server SQL server, Reporting Services

1 client machine (ternminal server)

I had to enable kerberos on all services. (some issue here? mm)

ok, it is all information that can obtain.
any idea?

Thanks in advance.
