Tableau 2020.2: High viz data quality warnings on Server & Online

0:00In Tableau 2020.2 Tableau have added the

0:02ability to add high visibility data quality

0:06warnings.

0:07This basically means that any quality

0:08warnings that you've added on the data set

0:11become highly

0:12visible in a view. That sounds like a

0:14complete tongue twister, absolute jargon,

0:17but let's have

0:18a go at showing you what that actually

0:20means. Okay, I'm going to go into a

0:22visualization. I'm

0:23going to go to this one you can see here

0:26where I built an example link out to a

0:28Salesforce item.

0:29Okay, the key thing here is I want to see a

0:31data quality warning here in context of

0:34this

0:34visualization to tell me if there's any

0:37issues with the data set. I'm in the

0:38visualization. I

0:39don't see anything here right now. Now what

0:42I could do is I could go back one step and

0:44look at

0:45my views. So this is typically how it

0:47access the views, but not many people think

0:50to go to data

0:51sources and just to check if there's any

0:54issues on this particular tab or even

0:56better go back to the

0:58lineage which is part of the data

0:59management add-on and actually just check

1:01if there's any

1:01sort of historical issues or challenges

1:04that this particular data source presents.

1:06So what Tableau

1:07have done is they've added the ability for

1:09you as an administrator or an owner of a

1:11data set

1:12to add high visibility warnings and so let

1:14me just show you how that works. At the

1:16moment you'll see

1:17that this column here on the left hand side

1:19with this exclamation mark is empty. There

1:22's nothing

1:22there and this is where typically the

1:24quality warnings would appear. So let me

1:26just zoom out a

1:27little bit and let's just set one of these

1:29up. I'll tick quality warning and you'll

1:31see here

1:32that I have the ability to enable the

1:34warning. I can choose what kind of warning

1:36I want. I'm going

1:37to just set a standard warning and I'm

1:39going to make this highly visible okay and

1:42I'll basically

1:43just type something sort of basic in here.

1:46Okay I'll just put a generic one. Obviously

1:49you'd need

1:50more descriptions in there but bear in mind

1:51that users will actually be able to see

1:53this and you

1:54have 4,000 characters so you can actually

1:56put quite a lot of detail in there. Okay so

1:58we've added this

1:59quality warning. I'm just going to hit save

2:02so it persists that warning and now you can

2:05actually see

2:05two things. You get this toast icon here at

2:08the top. This is a toast notification

2:10actually. I can

2:11clear that away now that I've understood

2:13that the notification is there and then I

2:16now get this new

2:17indicator here on the left hand side to

2:18tell me that there's a warning and when I

2:20click on that

2:21I actually get some context. Okay so all

2:24the information I typed there, the date,

2:26who's typed it

2:27and the warning is all available to me as a

2:31user. Okay so now the real secret is if I

2:34go into a

2:35dashboard with this particular data source

2:37used will I get that warning? Let's have a

2:40look and see.

2:41So let's go back to the home page.

2:42Previously we were looking at this

2:44particular view. When I

2:45click on it for the first time I go

2:47straight into it but notice I get this

2:50notification straight

2:51away. Important data quality warnings

2:54affect this view and if I open the data

2:56details you'll see that

2:57that's also available there but when I zoom

3:00out it's over here on the right hand side.

3:03So this

3:03information that I've typed in actually

3:06sits in context with my view. So if there's

3:08issues with

3:08a field or a calculation or any particular

3:11problem with that database, maybe the data

3:13is stale and

3:14you know refresh isn't updating as often as

3:17it should do, those notifications actually

3:19come up

3:20here and they get full context as to what's

3:22happening. That's really important for

3:25transparency

3:26with your data sets especially in the

3:28business where data can change really

3:29really really fast.

3:31Okay if you want to hide this you can just

3:33hit x if you want to bring it back you can

3:35actually see

3:35the data details here so you can always

3:37bring that back as and when you need to if

3:39you see this icon

3:41enabled. That's pretty much the feature in

3:43a nutshell, if you've enjoyed this video
