Endorsement in Power BI, Part 2, How to Endorse?

Endorsement in Power BI, Part 2, How to Endorse?

In the previous post I explained the basic concepts around endorsement in Power BI. We discussed that users’ ability to collaborate in creating and sharing artifacts is one of the key aspects of users’ experience in Power BI. But it would be hard, if not impossible, to identify the quality of the artifact without a mechanism to identify the artifact’s quality in large organisations. Endorsement is the answer to this challenge. We discussed the following in the previous post:

In this post, I explain the following:

How do Power BI administrators enable certification and grant rights to security groups?

In the previous post, we discussed that a Power BI administrator must enable certification and grant sufficient rights to the security groups. Therefore, all members of the specified security group are authorised to certify the artifacts. If you are a Power BI administrator, follow these steps to do so:

  1. After logging into Power BI Service, click the Settings button
  2. Click Admin Portal
  3. From the Tenant settings, scroll down to find the Export and sharing settings
  4. Find and expand the Certification setting
  5. Enable certification
  6. Put the certification process documentation URL (if any)
  7. It is not recommended to enable this feature for the entire organisation. So, select the Specific security groups option
  8. Type the security group name and select it from the list
  9. Click the Apply button

The following image shows the above steps:

It may take up to 15 minutes for the changes to go through. After that, all the members of the specified security can certify the artifacts. In the next section, we see how to certify the supported artifacts.

Note

Everyone who has “write” permission on the Workspace containing the artifact can promote it. Therefore, the users or security groups with one of the AdminMember, or Contributor roles in the Workspace can promote the artifacts.

However, one should not promote the artifacts just because he/she can. The organisations usually have a promotion process to follow, but the boundaries around promoting are often much more relaxed than certifying it.

Content Endorsement in Power BI, Part 1, The Basics

As you may already know, Power BI is not a report-authoring tool only. Indeed, it is much more than that. Power BI is an all-around data platform supporting many aspects you’d expect from such a platform. You can ingest the data from various data sources, transform it, model it, visualise and share it with others. Read more about what Power BI is here.

One of the key aspects of users’ experience in Power BI is their ability to collaborate in creating and sharing artifacts, making it an easy-to-use and convenient platform. But the convenience comes with the cost of having a lot of shared artifacts in large organisations raising concerns about the artifact’s quality and trustworthiness. It would be hard, if not impossible, to identify the quality of the artifacts without a mechanism to identify the quality of the artifacts. Endorsement is the answer to this.

In this series of blog posts, I answer the following questions:

But before we start, we need to know what content means in Power BI.

What does Content Mean in Power BI?

Update:
Microsoft lately updated the “Content” terminology, which is slightly different from when I wrote this blog. So I replaced content with artifact that is a more generic term. While the term content is not relevant to the topic anymore, I decided to keep this section explaining what content means in Power BI.

When we use the term Content in the context of Power BI, we refer to the artifacts related to visuals in Power BI Service. We currently have the following artifacts in Power BI:

From those artifacts, the Reports, Dashboards and Apps are Contents.

Dynamically Passing Parameters to a SQL Stored Procedure in Excel 365 Using Power Query

In September 2014, I wrote a blog post on dynamically passing parameters from PowerPivot to a SQL Server stored procedure using VBA. Back then, VBA was a real lifesaver. It perhaps still is for many of us. But frankly, I even forgot how to write VBA. Maybe it is time to look at it again. I also wrote a quick tip in August 2020 about doing a similar thing in Power BI using Query Parameters. Check it out if you’re keen to know how it works in Power BI.

Eight years later, one of my weblog readers asked how to do the same thing in later versions of Excel; he is specifically asking for Excel 2019. I thought it would be good to cover this topic after 8 years and see how it works now. So, here it is, a new blog post.

The Problem

From time to time, Excel users require to get the data from a SQL Server stored procedure. The stored procedures usually accept some input parameters and return the results. But how can we dynamically pass values to the stored procedures from cells in Excel to SQL Server?

Prerequisites

For this blog post, I use SQL Server 2019 and Microsoft’s famous sample database, AdventureWorks2019. You can find Microsoft’s other sample databases here. I also use Excel 365, it should work the same way in Excel 2019, though.

The Solution

I discuss two approaches to overcome the challenge. Both approaches use Power Query slightly differently. In both approaches, we parameterise the SQL Statement of the SQL Server connector, passing the values to the parameters from an Excel table. One approach requires ignoring the Privacy Levels in Power Query, while the other does not. Both approaches work, but, depending on your preferences, you may prefer one over the other.

As mentioned, I use the AdventureWorks2019 sample database that contains a couple of stored procedures. I use the dbo.uspGetBillOfMaterials stored procedure accepting two parameters, @StartProductID and @CheckDate.

Approach 1: Parameterising the SQL connector’s SQL Statements, Ignoring Privacy Levels

Follow these steps to pass the parameters’ values from an Excel sheet to the stored procedure and get the results in Excel:

  1. In Excel, navigate to the Data tab
  2. Click the Get Data dropdown
  3. Hover over the From Database option and click the From SQL Server Database
  4. Enter the Server
  5. Enter the Database
  6. Expand the Advanced options
  7. Type EXEC [dbo].[uspGetBillOfMaterials] @StartProductID = 727, @CheckDate = N'2013-01-01' in the SQL statement textbox
  8. Click OK

  1. Click the dropdown on the Load button
  2. Click Load to
Load to Options to Load the Results of Power Query query into an Excel Sheet or PowerPivot Model

From here, we have some options to load the results either into an Excel sheet or the PowerPivot data model. We want to load the data into the PowerPivot data model in this example.

  1. Select Only Create Connection
  2. Check the Add this data to the Data Model option
  3. Click OK

Slowly Changing Dimension (SCD) in Power BI, Part 2, Implementing SCD 1

Slowly Changing Dimension (SCD) in Power BI, Part 2, Implementing SCD 1

I explained what SCD means in a Business Intelligence solution in my previous post. We also discussed that while we do not expect to handle SCD2 in a Power BI implementation, we can handle scenarios similar to SCD1. In this post, I explain how to do so.

Scenario

We have a retail company selling products. The company releases the list of products in Excel format, including list price and dealer price, every year. The product list is released on the first day of July when the financial year starts. We have to implement a Power BI solution that keeps the latest product data to analyse the sales transactions. The following image shows the Product list for 2013:

Products List 2013 in Excel
Products List 2013

So each year, we receive a similar Excel file to the above image. The files are stored on a SharePoint Online site.

Scenario Explained

As the previous post explains, an SCD1 always keeps the current data by updating the old data with the new data. So an ETL process reads the data from the source, identifies the existing data in the destination table, inserts the new rows to the destination, updates the existing rows, and deletes the removed rows.

Here is why our scenario is similar to SCD1, with one exception:

  • We do not actually update the data in the Excel files and do not create an ETL process to read the data from the Excel files, identify the changes and apply the changes to an intermediary Excel file
  • We must read the data from the source Excel files, keep the latest data while filtering out the old ones and load the data into the data model.

As you see, while we are taking a very different implementation approach, the results are very similar with an exception: we do not delete any rows.

Implementation

Here is what we should do to achieve the goal:

  • We get the data in Power Query Editor using the SharePoint Folder connector
  • We combite the files
  • We use the ProductNumber column to identify the duplicated products
  • We use the Reporting Date column to identify the latest dates
  • We only keep the latest rows

Getting Data from SharePoint Online Folder

As we get the data from multiple files stored on SharePoint Online, we have to use the SharePoint Folder connector. Follow these steps:

  1. Login to SharePoint Online and navigate to the site holding the Product list Excel files and copy the site URL from the browser
Getting SharePoint Online Site URL
Getting SharePoint Online Site URL
  1. From the Get Data in the Power BI Desktop, select the SharePoint Folder connector
  2. Click Connect

  1. Paste the Site URL copied on step 1
  2. Click OK
