0:00In 22.4 in Tableau Prep, you can now just

0:03replace an input by dragging the file on

0:05top of the existing connection.

0:08It's a small quality of life improvement,

0:09but it's so valuable. Let me show you how

0:11it works. Let's get started.

0:13Before we get stuck in, just one quick

0:14favor. 82% of the people watching this

0:17video in the last year aren't subscribed to

0:20the channel.

0:20And just to show you some context, nearly

0:22half of my subscribers came from this last

0:24year's worth of content.

0:26And if you look at how many views and how

0:27much time people are spending, I'm sure it

0:29's creating value somewhere.

0:31So if you really appreciate the content or

0:32would like to see even more of it at a

0:34better, higher quality standard, hit the

0:36sub button and enjoy the rest of the video.

0:38So here we are in a prep flow. You can see

0:40that I already have errors here. I've got a

0:42file that is missing.

0:43I essentially broke this flow just to show

0:45this example. This is the default workflow

0:47that you get with Tableau Prep when you

0:49open it up.

0:50It's the very first Superstore flow. Now

0:52here you can see we've already got a

0:53connection that's broken.

0:55So what I'm going to do is I'm going to go

0:56and get the exact same file that I moved to

0:58another location.

1:00In this case, let's assume that I'm new to

1:01the organization. I don't have access to

1:03this file.

1:04So what I'm going to do is I'm first going

1:06to go and get my finder window just so we

1:08can bring up the relevant data source on

1:10screen.

1:11You can see here I've got this returns data

1:12set.

1:13So all I'm going to do is I'm going to drag

1:14it into my connection window here on the

1:16left and you'll see that Tableau

1:18automatically adds it to the window.

1:20And you can see here I have a returns.xlsx

1:22file here and I have the returns table just

1:25here.

1:26And it's going to replace this top one over

1:28here. Now what I could have done, I could

1:30have fixed this by editing this connection,

1:32referencing the new file.

1:33But what I've done is I've just brought it

1:34in again to show you this basic feature. I

1:37can go ahead and drag it and I can replace

1:39it.

1:40There's this little icon here that says

1:41replace. I drop it on top and now Tableau

1:43will go and replace everything.

1:45You'll see the errors disappear just like

1:47magic. So nice, so useful. Great quality of

1:50life improvement. Love to see it.

1:52Now there's a couple of other subtle

1:53changes. If you're familiar with Altrix,

1:55you'll notice that Tableau prep has got

1:57these curvy lines.

1:58And this is part of a feature set that I

1:59don't fully understand the impact of until

2:02I start using this.

2:04It'll probably take me a couple of weeks of

2:05using prep frequently to understand what

2:07these changes are.

2:08But if I go ahead and bring up the notes

2:10for this particular capability, it's

2:12essentially a UI improvement.

2:15Let me put it up on screen here so you can

2:16see what I'm looking at. I actually covered

2:19this in my coming soon video for this

2:20particular release.

2:22Tableau prep makes the process of building

2:24a flow to clean and shape your data

2:26incredibly visual with a revamped flow edge

2:30graph.

2:31I don't know what that means. Flow edge

2:33graph. I'll come to that in a second.

2:35We are reducing visual distractions that

2:37arise when the flow graph becomes larger

2:39and more complicated.

2:41These changes will provide you with a more

2:42legible, flexible and playful experience

2:44when creating flows.

2:46I think part of that changes the curvy

2:47lines, but I think more importantly, if you

2:50ever work with a really, really large flow,

2:52I can't show you any examples.

2:53I do have large flows, but their client

2:54works. I can't show them to you.

2:57Tableau prep gets a bit funny in the edges

2:59and the extremes. I wonder if this tries to

3:03resolve those issues. I wonder if it

3:05resolves the jittery, janky behaviour

3:07sometimes we get.

3:08I'm not entirely sure, but I think that's

3:09what they're trying to resolve in this

3:11particular release.

3:13Let me know what you think they're going to

3:14solve in the comments below. If you know

3:16the answer, also put them in the comments

3:17below. I'd love to hear them.

3:19That's it for Tableau prep in this release.

3:21I've actually got another video about Lock

3:22Shark for Tableau prep. That's a separate

3:24video.

3:25It deserves a certain air time. Thanks for

3:27watching and I'll catch you in the next

3:28video.

Rollup

In Tableau Prep 2022.4 you can fix a broken or outdated input just by dragging a new file straight onto the existing connection, instead of manually re-editing it. It's a small quality-of-life change but removes a repetitive annoyance when files move or get renamed.

Tim opens a Prep flow (the default Superstore starter flow) where an input file reference has been deliberately broken to show the error state. He then locates the actual data file and demonstrates fixing the connection.

The Breakdown

Spot the broken input 0:40

When a source file has moved or been renamed, Tableau Prep flags the connection with an error rather than removing it, so you can still see and interact with the broken step in your flow.
Drag the replacement file onto the connection 1:00

Locate the correct file in a finder window and drag it directly into the connections pane on the left; Tableau Prep adds it and shows a 'replace' icon when you hover it over the broken connection.
The old method still works 1:32

You can still fix a broken connection the traditional way, by editing the connection and pointing it to the new file location; the drag-and-drop swap is just a faster alternative.
Drop to swap and clear errors 1:40

Dropping the file onto the existing connection replaces it outright and the errors disappear automatically, without you touching any downstream steps in the flow.
Possible fix for large-flow glitchiness 2:41

Tim suspects the redesign may also address the jittery, janky rendering behaviour Prep sometimes shows in very large or complex flows, though he can't confirm this without more real-world use.

Worth Knowing

Tim admits he doesn't yet know the practical impact of the new curvy flow-edge graph and expects it'll take weeks of regular use to judge.
He can't show examples of the large, complex flows where the edge-graph change might matter most, since those are client work.

Use It When

Reach for this when a Prep flow's source file has moved, been renamed, or you're rebuilding a flow with a new but structurally identical file, and you want to avoid manually re-pointing every broken connection.
