Links to Power BI Mobile Reports or Apps

/0 Comments/in /by

You have deployed your Power BI reports/apps and now management is eager to use them. But how do you provide an easy one-tap shortcut for them to launch a specific report or app on mobile devices and open them in Power BI Mobile? For example, in a recent project, we had to provide executives with an easy “button” to see their executive dashboard on iPhone/iPad. To make things more interesting, the ask was to auto-provision “the button” so the users don’t have to create it manually.

Each approach has specifics controlled by the operating system on the device. Your best option will probably be Siri or Android shortcuts.

  1. Siri or Android shortcuts – Use this option when you want the user to initiate the link either by clicking on it or by speaking the associated phrase. For more information, read “Using Siri Shortcuts in Power BI Mobile iOS App” and “Use Android app Shortcuts in the Power BI Android app” The downside of this approach is that Apple doesn’t currently have shortcut APIs so you can’t provision the shortcuts, such as by using Microsoft Intune or AirWatch. In other words, the user must manually create the shortcut within Power BI Mobile. However, they can send the shortcut to other users as “untrusted shortcut”.
  2. Redirect links – Use this option when you want the device to prompt the user to install the app if it is not already installed. For more information, read “Create a link to a specific location in the Power BI mobile apps“. The steps to create a shortcut are device specific. In this project, the client used AirWatch to provision “weblink/webclip” icons to launch the redirect links. The caveat for using redirect links is that the user will be always prompted to “close” the prompt or open the app, and as far as I know, there is no way to bypass this prompt.
  3. Universal links – Luckily, Power BI supports iOS universal links. Just navigate to the report in the browser, copy the link, and associate it with an icon. The old way to create the link, which is still supported, was to use the mspbi scheme, such as mspbi://app/OpenReport?appId=1f3d811e-8d6c-4708-9034-ad5c2db1615b&reportObjectId=16c484cd-d2b2-40ab-bddc-3cb97b62e518. Choose this option when you want to bypass the prompt asking the user to open the app. Universal links work if the link is in email message, Siri shortcut or some other app, such as Notes. The downside is that if the user creates a “weblink/webclip” shortcut with the link using the “Add to Home screen” feature or auto-provision with AirWatch, the shortcut will always open in the browser and bypass Power BI Mobile. In other words, the link won’t work when launched from a “weblink/webclip” shortcut.

Let’s summarize the three approaches.

OptionProsCons
Siri or Android shortcuts

(Recommended)

No prompt, can be voice activatedSince there are no APIs to work with shortcuts, they can’t be automatically provisioned
Redirect “deep” linksAsk the user to install the app if not presentAlways prompts the user to “close” or open Power BI Mobile.

Analyzing Microsoft Teams Data

/0 Comments/in /by

More and more organizations are switching to Microsoft Teams mostly for online meetings. However, Microsoft Teams can deliver much more than that and it will be unjust to compare it with other popular meetings apps. What Microsoft has done with Teams is amazing! Now that I got to study and program Microsoft Teams, I have found it a powerful and extensible platform. For example, Microsoft has provided add-ons for common verticals, such as Teams for Education. Microsoft Teams can be further enriched with apps and can be used to centralize all these Excel spreadsheets that are floating around. And the best of it: most of the Microsoft Teams data is exposed via a single data source: Microsoft Graph API, with the caveat that it is not that easy to get the data out.

I’ve added a new case study “Public School District Gets Insights from Microsoft Teams” that shows how Prologika helped one of the largest public school districts in the Atlanta Metro area to derive insights from Teams. They struggled for a long time trying to get the necessary data from Microsoft Teams to analyze how effectively teachers and students utilize Microsoft Teams in these challenging times. Prologika developed a custom app to extract the required data by calling the Microsoft Graph APIs. The key solution benefits were:

  • Automated daily retrieval of Teams data
  • Enabled a digital feedback loop to learn from the gathered insights and improve operations
  • Ability to analyze educational data by various perspectives (school, class, teacher, student, assignments, submissions, and events)

Showing Database Images in Power BI and Tabular

/0 Comments/in /by

The Power BI image-rendering visualizations, such as Table or Card, expect image links to public servers hosting the images with anonymous permissions. This has obvious shortcomings. Can we load images from a database or Power BI data table? You bet, as Jason Thomas has demonstrated a long time ago. Here are the steps I followed to show the images from the Production.ProductPhoto table in the AdventureWorks2012 (or later) database. If you want to embed a few images into a Power BI data table (instead of an external database), you can convert them manually to Base64 using any of the online image converters, such as https://codebeautify.org/image-to-base64-converter and embed the resulting string into a Power BI data table (the Enter Data feature). Gerhard Brueckl takes this one step further by showing you how to automate the base64 conversion with many images.

  1. Import the table with the image column as usual in Power BI.
  2. In Power Query, change the data type of the image column to Text.
  3. Add a new custom column that prefixes the base64 string with “data:image/jpeg;base64,” (not the comma at the end) for jpeg images or “data:image/png;base64,” for png.
    = Table.AddColumn(#”Changed Type”, “ProductImageEncoded”, each “data:image/jpeg;base64,” & [ThumbNailPhoto]).
    The ProductImageEncoded column below shows what the final Power Query transformation should look like. Click Close & Apply to import the table in the data model as you’re done with the transformation part.
  4. In Power BI Desktop, select the ProductImageEncoded field in the Fields pane. Assuming the new ribbon, in the Column Tools ribbon, change the field category to Image URL.
  5. Add the ProductImageEncoded field to a Table, Card, Multicard, or Slicer visuals.

Power BI Time Adventures

/0 Comments/in /by

A customer reported that a Power BI date filter/slicer set to a specific date in Date dimension, let’s say April 24, 2020, doesn’t return some rows from the fact table that match that date. Upon some digging, the data was imported from Dynamics CRM and the source date column had UTC time. Power Query showed Date/Time/Timezone as a data type. However, the developer has converted the corresponding field in the model to the Power BI Date data type to remove the time portion. And indeed, the Data View would show that date as April 24, 2020 (without the time portion). So, why no match?

The xVelocity storage engine (the storage engine behind Power BI and Analysis Services Tabular) has only one data type for dates: DateTime. If you convert the field in the data model to Date, it still keeps the time portion (UTC or not) and it doesn’t change the column storage. It just changes to the column formatting to show the date only.

To get rid off the time portion, cast to Date in the data source (e.g. in a wrapper SQL view) or change the data type of the column in Power Query to Date. This will “remove” the time portion. In reality, xVelicity will convert the time to midnight.

Overview:Time-Intelligence refers to analyzing calculations and metrics across time and is the most common type of business intelligence reporting. Power BI has a lot of built in capabilities to help you get started but these alone are not always enough for most real-world solutions.

The key to mastering time-intelligence in Power BI is a good date table and understanding how to manipulate the filter context. This session will teach you how to do both!

In this (demo-heavy) session, we’ll quickly review Power BI’s built-in time intelligence capabilities and why you should avoid them! We’ll also cover the importance of a good date table, what attributes it should include, and how it can be leveraged to simplify complex time-intelligence calculations. Finally, we’ll breakdown a handful of the 40+ DAX time-intelligence functions, showing you how they work under the covers (hint: filter context) and how they can used in combination to accommodate complex business logic.

Speaker:Bill Anton is an independent consultant whose primary focus is designing and developing Data Warehouses and Business Intelligence solutions using the Microsoft BI stack. When he’s not working with clients to solve their data-related challenges, he can usually be found answering questions on the MSDN forums, attending PASS meetings, or writing blog posts over at byoBI.com.

Power BI Source Control

/0 Comments/in /by

Question: How to put Power BI files under source control?

Workaround: Power BI Desktop does not currently support source control and it doesn’t have an Excel-like extensibility mechanism to let developers take from where Microsoft left off.

However, thanks to the enhanced dataset metadata (currently in preview), you can implement a rudimentary source control policy while waiting for third parties to fill in the void by using these steps:

  1. In Power BI Desktop, go to File, Options and settings, Options. In the “Preview features” tab, check “Store datasets using enhanced metadata format” if this feature is still in preview. Restart Power BI Desktop when asked.
  2. In Power BI Desktop, go to File, Save As and save the file as a Power BI Template (*.pbit) file. This removes the imported data which you don’t need for source control and keeps the file small.
  3. If you want to put all artifacts (reports, queries, data model) under source control, upload the entire file to your source control provider. However, if you want to compare and restore the model schema, you have more work left.
  4. In Windows Explorer, right-click the pbit file and extract its content using your favorite extractor, such as 7-Zip. If this doesn’t work, rename the file extension to *.zip (Power BI files are saved as archive zip files) and extract.
  5. The DataModelSchema file stores the model schema. I recommend you version control it separately so you can easily compare what changes have been made to the model (DataModelSchema is described in the same JSON schema as Analysis Services Tabular).
  6. If you want to restore to a previous version of the schema or make changes, simply change the DataModelSchema file, zip the content back to a *.pbit file.

Other options to get to the model schema:

  1. Use Tabular Editor which can open *.pbit files.
  2. Use SSMS to connect to the running instance of Power BI Desktop (you can use the DAX Studio to obtain the port the AS instance is listening on) and then script the database as CREATE.
