title: Error connecting to Data Source in SSRS
body: <p>I am trying to connect to Datasource but getting this error:</p>
  
  <pre><code>An error occurred during local report processing. 
  An error has occurred during report processing. 
  Cannot create a connection to data source 'PO'.
  You have specified integrated security or credentials in the connection string for the data source, but the data source is configured to use a different credential type. To use the values in the connection string, you must configure the unattended report processing account for the report server.
  </code></pre>
  
  <p>Any idea how to resolve this?</p>
  
  <p>Thanks
