Hey Craig -
All this command is import the data source (connection string, fields, etc.) from a different workbook. You could do the same thing by saving the data source from that "other" workbook as a .TDS, and then dragging it into the current one.
so it is not for accessing the data in another workbook?
And to take things further, the other workbook doesn't really have data "in it", anyway - it's connecting to a data source itself via it's own data connection. All this feature is doing is grabbing that data connection (instructions on how to connect to the data and which fields / calcs to show) and bringing it over.
I've never really paid much attention to that feature, but now that you point it out, it could be named a little bit better, couldn't it? ....although I guess "Copy data source from another workbook" lacks a certain je ne sais quoi....
Jaynie says "koi"? Shewt, Tommy's first werd was "trout"! Just kidding
Interesting...just did some quick testing, definitely not thorough...
-- Connecting to a workbook that contains an extract (.twbx) WILL pull data from it. Security comes with it too so if a Refresh of the data or Connection edit is desired the user will be challenged for credentials. So good that security is there but now, from an admin point-of-view, you need to be aware that confidential information can be accessed by unauthorized personnel.
-- Connecting to a workbook that does NOT contain an extract (.twb) will, of course, not pull any data over. If the data connection is secured then user will be challenged before they can continue. Failure to authorize will NOT allow the connection to occur and no workbook will be created, you'll be left looking at the Tableau Desktop "Connect to Data" tab. Good, this is as I would expect.
