Hi All,
We have a number of dashboards connecting using different datasources. From the ocean of dashboards, I want to find the list of dashboards using a particular column in the workbook.
Before we remove columns from these tables though, we first need to be sure that no published and embedded/local datasources are still configured to pull data from those columns.
I was hoping to write a query against the local Tableau server Postgres metadata repository "workgroup" database, that would return details on which tables and columns our published datasources and workbook embedded/local datasources are configured to pull data from.
Is there any easy way that I can do this? If it is not clear what I am trying to do, please let me know.

Thanks Peter... When you say uploaded extracts, you mean Tableau Datasource(tds) right?
What if I am using custom SQL by connecting to redshift environment.. Will I be able to see all the columns in the workbook using the workgroups datasource.
I did some research on the workgroups database. Based on my research I am not able to find an answer for this problem.
