Error While deploying a simple report

Hi there,
I have created the simple report and trying to deploy the report to reporting server.
I am getting the below error. I have the SQL Admin rights on the database. Please advice

• An error has occurred during report processing.
  
  • Cannot create a connection to data source 'LtdDB'.
    
    • For more information about this error navigate to the report server on the local server machine, or enable remote errors

Thanks alot in advance!
