title: What is the difference between BigQuery Data Viewer permissions at dataset-level vs project-level when accessing the data from Data Studio?
body: <p>I have a dataset in BigQuery and if I give a user <strong>BigQuery Data Viewer</strong> permissions at <strong>dataset level</strong> he cannot see the data in Data Studio, he has an error when he tries to add a chart: &quot;<strong>Data Studio Configuration Error</strong>. Data Studio cannot connect to your data set&quot;.</p>
  <p>This error doesn't appear when I give the user the same access permissions(BigQuery Data Viewer) but at project level. In this case everything is working ok.</p>
  <p>In the documentation it says: &quot;You must have the appropriate permissions in order to add a BigQuery data source to a Google Data Studio report. In addition, <strong>the permissions applied to BigQuery datasets will apply to the reports, charts, and dashboards you create in Google Data Studio</strong>.&quot;</p>
  <p>What does it mean &quot;appropriate permissions&quot; ?</p>
  <p>Why is not working if I give the user access permission at dataset level? ( I don't want the user to have access to all datasets in the project)</p>
