I have a published data source from Tableau Online that updates daily using the Tableau Sync Client. Our data comes from a messy source that is also updated daily.
There are lot of misspellings in our data (thousands) that we solve using the handy "group" function.
However, when creating a a new report/workbook we have manually recreated these groups from scratch.
Is there a way to publish this "grouped dimension" back to Tableau Online?
Is there any reason you can't publish that data source back to Tableau Online and overwrite the existing data source?
