![]() Editing the Windows registry incorrectly can have harmful effects on your computer. Important: Always make a backup of the registry file before making any changes to it. plist (Mac) file, modify the settings you want to turn off and then use the modified file to create an automated script to push the updates to each computer where Tableau Desktop is installed. To deploy changes to remote computers, you can export the settings from the registry (Windows) or. plist file then restart the application to see your changes. To configure custom content for the Discover pane, replace sample workbook with custom samples, or to change settings after installation (both Windows and Mac), you can change the registry or. For a list of these features, see Install From the Command Line in Install Tableau Desktop and Tableau Prep Builder from the Command Line.įor Mac, you can configure custom discover pane content, replace default accelerator workbooks with custom workbooks, or turn some features off only after installation. ![]() As an administrator you can turn some of these features off.įor Windows, you can also configure custom content to show in the Discover pane, replace default accelerator workbooks with custom sample workbooks, and turn some features off during installation. But you might have some features that you don't want users to have access to, such as the ability to upload crash dump files and logs. For example, with Tableau Desktop, automatic product updates or the ability to automatically save user workbooks is included as part of the install. Then, the aggregated function is used to leave the values for each day, using as required aggregations such as: SUM (), MIN (), MAX (), AVG ().When you install Tableau Desktop and Tableau Prep Builder, there are several features that are turned on by default. The “Inner-Join” allows us to merge for each day of the original table, with the sales of the last 7 days (including the current day) of the second copy of the table. Step 6: Add step to generate the output file. IIF( = 7, ROUND( / 7, 2), NULL)ĭelete unnecessary fields: “Number of Rows (Aggregated)” and “Sales” In case you do not have the 7 days of history for a specific day, the value of the weekly average will be null. We already have the data to calculate the weekly sales average. Let’s review an example of the aggregation for the date of January 7, 2019. The key in this step is to group by the field of “Date” and aggregated or summarize: MIN (Sales of the Day), SUM (Sales) and Sum (Number of Rows (Aggregated)). Step 5: Data aggregation or summarization. But as the first 6 days of the table, do not complete the 7 days of a week, you must subtract 21 days (6 + 5 + 4 + 3 + 2 + 1), which are the days that were missing each of the dates to complete the 7 days, which results in 2,534 records. We multiply 365 records by 7 days, the result is 2,555. ![]() ![]() This results in 2,534 records from the original table of 365 records, the result of “Inner Join”. It is going to join each record of the first copy of the table, with the data of the 7 days of data of the week of the second copy. The key in this step are the clauses of the Join. Step 4: Perform “Inner Join” of both data tables. Step 3: Add a new copy of the original data. The newly created field type is changed to date, instead of date and time and the “Sales” field will be renamed “Sales of the Day”. The first step is to connect to the data file.ĭefine a new field with the value of the date of the day one week behind the original date. In preparation of data there may be multiple correct ways to achieve the same goal and it is very interesting to review the techniques of the rest of the participants to improve our skills and also to put into practice the new features that are released in Tableau Prep Builder.īelow I share the steps that I followed to solve this challenge using Join and Aggregates. The input data file contains two fields: 1) Date, and 2) Sales. The output data file must contain: 1) Date, 2) Sales of the day and 3) Average sales of the last 7 days. The week 22 exercise challenges us to obtain averages of the last 7 days in sales. The challenges of Preppin’Data are weekly challenges published by Carl Allchin and Jonathan Allenby to help us in the development of our skills in Tableau Prep Builder through which we put into practice and explore different functionalities and techniques. I’m very happy, as this is my first blog about Data Preparation in Tableau Prep Builder and it’s about one of the challenges of Preppin’Data.
