2022: Week 38 - Solution


Solution by Tom Prowse and you can download the workflow here.


The challenge this week focusses on recreating the standard Salesforce connections that are available in Tableau Desktop. For this challenge, you can create your own Salesforce account and use the Salesforce connector, or alternatively use the text files provided. For this solution I have used the text files but they will be the same if you are connecting via Salesforce.

Step 1 - Remove Fields

The first step that we need to do this week is input our 3 tables, and then select the fields that we need. We can remove a lot of the unneeded fields at the input step stage, therefore we need the following from each table: 

Opportunity
- OpportunityID
- AccountID
- Opportunity Name
- Stage Name
- Amount
- OwnerID
- CreatedByID

User
- ID
- Name

Account
- AccountID
- Account Name
- Account Type
- OwnerID (Rename to AccountOwnerID)
- CreatedByID (Rename to AccountCreatedByID)

Step 2 - Opportunity & Users

For the first section we want to focus on the Opportunity and User tables. We want to recreate the joins so that we can associate a name with the Created By ID and Owner ID fields.

To do this we need two joins: 

Created By ID
Inner join where CreatedByID = ID


Here we can also rename the field Name to Created By Name, and then remove the ID field.

Owner ID
The second join that we need is an inner join where OwnerID = ID 



Again, we want to rename the Name field to Owner Name and also remove the ID field. 

Our table should now look like this:



Step 3 - Opportunities & Accounts

Next we want to start including the Accounts table into our workflow. We again need another join, but this time we are joining for our workflow with the Account table where AccountID = AccountID


We then want to include the Account Created By name, therefore we want to join our existing workflow back to the User table. This time it's an inner join where Account Created By ID = ID 


The final join involves finding the Account Owner Name, therefore we again need to join back to the User table. This is an inner join where Account Owner ID = ID



We can then remove any additional ID fields and rename the correct Name fields so our table looks like this:


This is our first output and the standard opportunities connection in Tableau Desktop.

Step 4 - Additional Outputs

Now we have the standard connection we can start to create the aggregated tables for the other outputs. Each of the aggregates will appear on a separate branch.

Who is the Opportunity Owner with the Highest Amount? 

Here we need to aggregate to group by Owner Name then Sum the Amount field.


This is Output 2: 


Who is the Account Owner with the Highest Amount? 

Again we need to aggregate, but this time group by Account Owner Name and again sum the Amount:



Here's Output 3:


Which Account has the most Opportunities & Amount? 

The final output we need to aggregate by grouping by Account Name, then sum the amount and count distinct on Opportunity ID. 


We can then rename the Opportunity ID to Number of Opportunities.

Here's Output 4:


The full outputs can be downloaded here.

Created by: Carl Allchin Welcome to a New Year of Preppin' Data challenges. For anyone new to the challenges then let us give you an overview how the weekly challenge works.  Each Wednesday the Preppin' crew (Jenny, myself or a guest contributor) drop a data set(s) that requires some reshaping and/or cleaning to get it ready for analysis.  You can use any tool or language you want to do the reshaping (we build the challenges in Tableau Prep but love seeing different tools being learnt / tried). Share your solution on LinkedIn, Twitter/X, GitHub or the Tableau Forums Fill out our tracker so you can monitor your progress and involvement The following Tuesday we will post a written solution in Tableau Prep (thanks Tom) and a video walkthrough too (thanks Jenny) As with each January for the last few years, we'll set a number of challenges aimed at beginners. This is a great way to learn a number of fundamental data preparation skills or a chance to learn a new tool — New Year...

 Created by: Carl Allchin Welcome to a New Year of Preppin' Data. These are weekly exercises to help you learn and develop data preparation skills. We publish the challenges on a Wednesday and share a solution the following Tuesday. You can take the challenges whenever you want and we love to see your solutions. With data preparation, there is never just one way to complete the tasks so sharing your solutions will help others learn too. Share on Twitter, LinkedIn, the Tableau Forums or wherever you want to too. Tag Jenny Martin, Tom Prowse or myself or just use the #PreppinData to share your solutions.  The challenges are designed for learning Tableau Prep but we have a broad community who complete the challenges in R, Python, SQL, DBT, EasyMorph and many other tools. We love seeing people learn new tools so feel free to use whatever tools you want to complete the challenges.  A New Year means we start afresh so January's challenges will be focused on beginners.

How to...Handle Free Text

Image
Free isn't always a good thing. In data, Free text is the example to state when proving that statements correct. However, lots of benefit can be gained from understanding data that has been entered in Free Text fields. What do we mean by Free Text? Free Text is the string based data that comes from allowing people to type answers in to systems and forms. The resulting data is normally stored within one column, with one answer per cell. As Free Text means the answer could be anything, this is what you get - absolutely anything. From expletives to slang, the words you will find in the data may be a challenge to interpret but the text is the closest way to collect the voice of your customer / employee. The Free Text field is likely to contain long, rambling sentences that can simply be analysed. If you count these fields, you are likely to have one of each entry each. Therefore, simply counting the entries will not provide anything meaningful to your analysis. The value is in ...
