# Tableau
This feature provides a comprehensive impact analysis of dbt™ changes on your Tableau environment. When you open a pull request (PR) in your dbt™ project, you can visualize the downstream effects of your changes across various Tableau assets.
### Key Benefits:
1. Identify which dbt™ model changes are impacting your Tableau assets.
2. Proactively communicate which Tableau data sources and calculated fields are affected by your dbt™ changes before going into production.
3. Discover which workbooks and dashboards might be impacted by the changes.
### Prerequisites:
1. Complete [Lineage Diff setup prerequisites](/app-help/documentation/bolt/ci-cd/lineage-diff.md#setup-instructions)
2. Connect Tableau to Paradime via the [Tableau integration](#prerequisites)
## How to Use
When a PR is opened in GitHub, an automated comment is generated listing all downstream Tableau nodes (Data Sources, Worksheets, Dashboards, etc.) that would be impacted.
Using the links available in the "Tableau nodes impacted" section, you can confidently investigate each node within Tableau before merging the PR changes into production.
