Can anybody tell me whether there are existing tools that I can use within Tableau Desktop or Tableau Server, where we can generate a report of which fields in each source are and are not being used?
More often than not, we are forced to simply connect and extract data sources, and deliver something very quickly. In these cases, we aren't given enough time to only bring in the fields we need. So we end up with lots of fields we aren't using which has some performance drawbacks as the sources get larger. If I bring in 100 fields and I only use 20, how can I easily identify which 80 fields I can go back and remove from the extracted source?
