Restitch the Tableau logical data layer and the Data Catalog physical data layer

After you completed stitching, there might be changes in Tableau or in the data source. For example, Tableau may have a new report and the data source may have a new column. To make sure that the lineage diagrams are also updated, you can restitch the data layers.

Prerequisites

• You have previously stitched Tableau's logical data layer and Data Catalog's physical data layer.
• You have a resource role with the Configure external system resource permission, for example Owner.
• You have a global role with the Catalog global permission, for example Catalog Author.
• You have a resource role with the Attribute > Add resource permission.

Steps

1. Ensure that Tableau's logical data layer is synchronized.
2. Ensure that Data Catalog's physical data layer is refreshed.
3. Open the Tableau Data Model asset page.
