I have created a tableau data extract from the one of the RDBMs data source and then published the same on tableau server.
Now I am using the published data source as my data connection in multiple tableau workbooks.
In all the workbooks I am using Tableau user filters at different level for example-: at region, product, branch.
For one particular workbook I applied the user filter at region level and selected "apply to all using this data source".
Now my concern is that will this action("apply to all using this data source") effect other workbooks which are also using the same data source but having user filters at different level, say "at product level".
No. Apply to all using this data source is limited to the workbook only. Give it a test yourself and you'll see
