Click on this data icon & select where it resides, if it is tableau server go to "tableau server" tab or if it is in your local goto to "other file",browse it manually it will add in your workbook.
Hi Andrew, that works, thx a lot!
how about say my data source A is a left join from file X and file Y and now I have updated my file X and Y and I have created extract for both X and Y individually. I would like to insert extract X and Y to the workbook and left join them together again and then replace data source A with this new left join (X and Y) data, how can i do this? also, I created some calculated fields for my data source A initially. So, if it's able to replace with the new left-join data, would the calculated fields still remain? i know this has something to do with optimizing the extract but i'm not sure with the procedure to do it.
If I have understood correctly then you have an extract file which is placed some where in your laptop or desktop and now you have created new dashboard with some other data extract but you want to use that one also in your new workbook. If so then please follow below steps.
Click on below yellow highlighted button in Tableau
After clicking on Yellow button you will get a popup window
Click on other files : again a popup window will appear to your screen
Now you can refer to that location where you have kept your .tde file like below screen
This is how you can connect Tableau extract file.
You're not able to left join extracts, only blend them. You can perform the left join when bringing your data into Tableau. Sounds like you'd be better keeping data source A.
From my understanding you need to do some data modelling with the new data extracts for that go the data extracts and right click and go to "Edit Data source" as per the screenshot and do the changes.
