After setting up SSRS as extra instans accordingly to below guide.
technet.microsoft.com/.../hh389760.aspx
First i had problems with deployment of reports. (se my other post)
"Publish Reports on Single Server with multiple SSRS instances".
But after using the powershell command with string -ServicesAOSName XX@AOSServerName -ServicesAOSWSDLPort 810X it worked to deploy reports.
But now when i try to print report i get error "Failed to log on to Microsoft Dynamics".
Something is not connected correctly between reporting services and ax ?.
I use the same Account (domain) for BC Proxy,SSRS Service Account and SSRS Execution account.
