Quick start
Your SourceMedium dashboard is built in Looker Studio (formerly Google Data Studio).1
Use the page selector
Click the page dropdown (top left) or the navigation menu to switch between modules.
2
Set the date range
Use the date range picker (top right) to change the reporting period. It applies to every chart on the page, and each page opens with its own default date range.
3
Apply filters
Filter by channel, store, product, and other dimensions using the dropdown controls.
4
Hover for details
Hover over a chart to see exact values.
View vs. Edit mode
View mode (the default) lets you use filters and controls and hover for details. You cannot change the dashboard itself. Edit mode lets you change charts, add visualizations, and change data sources and calculations. It requires Editor permission. To build your own reports, data sources, or calculated fields, follow Google’s Looker Studio Help Center. To start from a SourceMedium template instead, see the template copy instructions and the template directory.Credential modes
A Looker Studio data source uses one of two credential modes to read data. Knowing which one is in use helps when a dashboard shows no data. Owner’s credentials (recommended): the dashboard reads data with the owner’s BigQuery permissions. Viewers see data without needing their own BigQuery access. Best for sharing dashboards broadly within your organization. Viewer’s credentials: each viewer needs their own BigQuery access and sees only the data they have permission to read. Best for dashboards with sensitive data that needs row-level security.SourceMedium dashboards typically use Owner’s credentials so your team can view data without individual BigQuery access.
Sharing
Permission levels
Share a report
- Click Share (top right)
- Enter email addresses or a Google Group email
- Choose a permission level

Share a data source
Data source access is separate from report access:- Viewer: can see field names and descriptions
- Editor: can rename fields, edit calculated fields, and change the connection
- Owner: can delete the data source and change ownership
Data source access is not the same as data credentials. Access controls who can change the data source configuration; credentials control who can see the underlying data.
Use Google Groups
For teams with five or more users, manage access with Google Groups. We recommend two groups:
Warehouse access is not part of this. It follows your SourceMedium workspace role, so invite people from Team instead.
Troubleshooting
Dashboard shows 'No data'
Dashboard shows 'No data'
Check these in order:
- Date range filter: is it set to a period with data?
- Other filters: are they excluding all data?
- Data source credentials: do they have BigQuery access?
- Contact SourceMedium support if the problem persists

Large date ranges and complex calculations slow performance. Try:
- Reducing the date range
- Using pre-aggregated metrics when available
- Removing charts you do not need from the page
