I walk through a new feature in Tableau 2021.4 that lets you edit published data sources directly in the browser, rather than the old nine-step process of pulling them into Desktop and republishing. I show editing relationships, using the new scratch pad to test calculations, and publishing changes back over the existing source.

## Key takeaways

- In Tableau 2021.4 you can edit published data sources directly from the browser via the edit data source button, replacing the previous nine-step knowledge base workflow.
- You can edit relationships and add tables (for example bringing in a returns table) without ever opening Tableau Desktop.
- The new scratch pad lets you test and modify calculations against the published data source before committing changes.
- Publishing your changes overwrites the existing source and pushes the update to everything connected to that published data source.
- Extract-based sources need to refresh before you can use the scratch pad, so a live connection can be quicker for testing.
