0:00Hey, it's Tim here. And in 2020.3, Tableau
0:05's continued to enhance a feature called
0:07dynamic
0:08parameters. This time, if you're an author
0:10of a workbook, you don't have to close the
0:12workbook and open it again to see the
0:14dynamic update happen. You can just do an
0:17extract
0:17refreshes normal and actually the parameter
0:20updates automatically. Let me show you how
0:22that works. If you remember, I did a video
0:24on this in 2020.1. Be sure to check that
0:27out
0:27in the description below. And it's also
0:29going to pop up here as a link on the
0:31screen. And
0:32in order to do this, I just need to go to
0:34edit data source and make sure that I'm
0:36connected
0:36to the right date source. Now, since the
0:38last video, 2020.2 has come out, and it's
0:42brought
0:42the ability to edit relationships. So if
0:44you're following along from my old video,
0:46you'll
0:46see this migrated data sort of symbol. You
0:49can actually just go ahead, remove this and
0:52bring in the orders table. That's all we
0:53need for this particular thing. So now it's
0:55working
0:56with a new relationship set up. We don't
0:58need to worry about that in the moment. Now
1:01, if
1:01we go back to our forecast view, it's going
1:03to recreate the extract. It's going to make
1:05sure the fields sit exactly as they are.
1:07And now you can see everything is still
1:09here as
1:10it's supposed to. Now we're pretty much set
1:12up. You can see that I have just three
1:14segments
1:14here. And if I click on this drop down here
1:17and edit the parameter, you will see the
1:19new
1:19feature that was added in 2020.1. Let me
1:22just highlight it for you here. When work
1:25book opens,
1:26for this particular parameter, update it
1:28from the segment. Okay, so we're now going
1:31to update
1:31the data source. I'm going to change the
1:33Excel file that we're connected to. So let
1:35's go
1:35here, edit data source. I'm going to go
1:37into this edit connection. And this time I
1:39'm going
1:40to switch to the original Superstore file.
1:43Click open. I did this thing where I named
1:46it slightly funny. I named it original main
1:48and original original. And we've all been
1:50there. Don't laugh. Let's go. So let's go
1:53back to the forecast. What I should expect
1:55to see is a date in 2020 at the very right
1:57hand side of the line. And I should also
1:59see
2:00that my segment and parameter driving those
2:02segments is also updated itself. So let's
2:05go ahead to the forecast tab. By doing that
2:07, it will trigger an extract refresher.
2:09There
2:09you go. You can see that I've got my date
2:11here, my new maximum in 2020. And if I go
2:14to consumer, you can see I've now got the
2:17new corporate segment without having to
2:19update
2:20the visualization. So this is great. It
2:22means that if you're an author, you can now
2:24build
2:24this and refresh the data and boom, your
2:27parameters automatically refresh. If you
2:30use this in
2:30the past, this is going to be a great time
2:32saver for you. It's a small quality of life
2:34improvement, but it's about time. It's long
2:36overdue. Okay, that's it. If you've enjoyed
2:39this video, check out some of the other
2:40content on the channel. Check out some of
