    Reuse datasource and make joins in new workbook

    Lotte van Slooten

      Hi all,


      In our company we make a similar workbook for several customers. The basis for these workbooks is a big datasource with a lot of joins. Then for most of the customers we need to add (= Join) some extra information which is customer specific.

      What I wanted to do is publish this basis datasource to tableau server and make a workbook per customer where we join this published datasource to some extra customer specific datasource. Unfortunately we found out that is not possible.


      So my question is what would be a way the reuse a scheduled datasource and still be able to make joins, keeping this in mind:

      The initial basis datasource is quite heavy to make due to it's joins. So I really would like to make this one time and reuse the result. Also if we need to change something in the datasource in the future I would like to do this one time.


      We had a couple of new ideas but did not get one of these to work so far:

      -     Create an extract from tableau desktop and use the extract as the next datasource. The problem is we do not know how the schedule the update of this extract.

      -     When we publish the datasource to tableau server I guess it has to be put somewhere. So can we connect to the file on the backend in a way we can still join to this datasource. Problem: Where are the files and which type of files are these.


      Any help would be much appreciated.

          Hi Lotte,


          Its very hard to understand what your question is so I'll answer the only one I could identify.


          Problem: Where are the files and which type of files are these.

          When you publish a datasource to tableau server, they go to the server equivalent of \documents\my tableau repository\Datasources\10.5\ on the server C drive. They will either be .hyper or .tde files depending on your version of Tableau.


          You will need to remember when publishing your dashboards to also re-publish the datasources using the Server > Publish Data Source > data source menu.
