why don't you try with a sample extract -only some rows- (for all your data sources) and once finished, you do refresh to update it all. From what kind of datasources are you making the extract? databases?
Can you please explain me the process of doing the sample extract?
Once i extract the few rows then how can i see the full data on the workbook once i publish into server??
i am hiding unused field and extracting the whole rows in the data source, i am doing extract from vertica database.
for example I have an excel and I connect it from Tableau and generate an extract with thise few rows:
Then I save the workbook with .twbx and close it.
Once finished, I update the excel with all the data that is needed to be uploaded - and then in tableau (open it again), you should go to the extract - right click - extract - update / refresh and wait until it is finished:
Another way, If you are using Tableau Server, is that you can upload the workbook (.twbx) and generate a connection to the database with the sample data. Then you create a schedule in order to refresh the extract and it is usually faster than the first solution. Obviously, the name of the source tables have to be the same.
This guides can help you with tableau server - extracts - schedule:
Hope this would help you!
i dont have any hold on my data source, its coming from vertica DB. i am still dont understand the way you explained will work in my situation ?
if i take only few rows in my extract and published how can i get rest of rows in dashboard??
the elaboration perfectly good for excel, but how can i applicable to DataBase ??
this is more from database solution, could you first leave only a few rows in your tables of vertica, then do the extract.
Once it is done, you update that tables with all your information - then you go to tableau and refresh the extract.
Yes i understood, Thank you Luis for your information.
Have a good day!!
