• Power BI Nested Hierarchical Labels

    September 18, 2016 / No Comments » / 600 Views

    In the latest Power BI Desktop update, Power BI introduced a new drill-down option. Previously, after enabling drill-down on a chart and clicking the double-arrow icon, the chart will drill down to the next field in the Axis area (or to the next level of a hierarchy if a hierarchy is added to the Axis area). A student attending my Power BI class asked me this week how to avoid aggregation across all years if the user drills down from Year to the Month level. A few days ago, the only option was to introduce another Month field that has the Year-Month combination, e.g. 2005 July, 2005 August, and so on. Now, with the new drill down style, the chart will nest the hierarchical levels so you don't have to add a new field. This behavior is similar to how Excel show categories nested in PivotChart.

  • New Custom Visual Developer Toolset

    September 11, 2016 / No Comments » / 478 Views

    One of the most prominent Power BI benefits is its extensible architecture that allows developers to integrate Power BI with custom apps and extend its capabilities, such by creating custom visuals. Having contributed one of the first custom visuals, the Sparkline custom visual, I can tell from experience that Microsoft does its part to ensure that the submitted visuals meets quality, security, and functionality best practices. As custom visual developers have probably noticed, the Power BI Dev Tools is deprecated in favor of the new Custom Visual CLI Developer Toolset. The announcement page enumerates the main benefits of the new toolset. Personally, I like that Microsoft has decoupled the tool from dependencies to the "visual framework" that the original Power BI visuals use. This allows developers to use whatever dev tool they like, such as Visual Studio Code or Visual Studio, to code custom visuals. I also like the better...

  • AzureML – Current State of Affairs

    September 9, 2016 / No Comments » / 2689 Views

    Organizations are showing increased interest in predictive analytics. A large retailer that is using Azure Machine Learning (or AzureML) has approached me to help them automate the process. I can't help it but compare AzureML with the Analysis Service Data Mining each time I look at it. It looks like both Microsoft and I agree at this point, that what used to be difficult was made simple and vice versa. On the upside, AzureML provides business users with a cloud environment for creating predictive solutions without involvement from IT. AzureML has more features than SSAS Data Mining. Now that the focus is on the cloud, we probably won't see future investments from Microsoft in SSAS Data Mining (and the Excel data mining add-in for that matter) which is currently limited to nine algorithms. By contrast, not only has AzureML many more algorithms but also it allows users to use R...

  • Power BI Governance Getting Better

    September 4, 2016 / No Comments » / 1342 Views

    Larger organizations are naturally interested in established procedures for data governance, retention, search and taxonomy. With the rising important of data analytics, such policies are equally important for BI artifacts. For example, a large organization wants to restrict users to access Power BI only from approved devices and/ or on premises. Although it doesn't match yet the SharePoint data governance features, Power BI is making strides in this direction. The tenant admin can access the Admin Portal page (log in to powerbi.com, then click Settings, Admin Portal) to: View Power BI usage metrics and utilization. This fulfills a similar role to the Power Pivot Management Dashboard in SharePoint. Manage users. Set global tenant permissions, such as the ability to publish content pack to the entire organization, allowing sharing content with external users, publish to web (anonymous access), export data, interact with R scripts, Cortana, Analyze in Excel, templates, create audit logs,...

  • “Enter Data” Feature in Power BI Desktop

    August 23, 2016 / No Comments » / 4462 Views

    Power BI Desktop has a very useful feature that lets you create tables by manually entering the data. This could be useful in a variety of scenarios, such as entering some reference data, defining KPI goals, creating simple lookup tables, or prototyping some data. If you're familiar with creating tables in Power Pivot by copying and pasting tabular data, think of Enter Data as the Power BI Desktop equivalent. However, Enter Data is more flexible because it lets you also the edit the data! This makes it more similar to the Power Pivot linked tables that automatically synchronize changes in the Excel source tables. Creating a new table is straightforward. You click the Enter Data button in the Home ribbon. Don't confuse this with the New Table button in the Modeling ribbon that allows to create a read-only table from a DAX table-producing expression. While entering the initial data and...

    Now that Power BI Desktop supports Row-level Security (RLS), modelers have a little predicament. On the desktop, the USERNAME() function returns the user's domain login (domain\login). However, when the model is deployed to powerbi.com, Username() returns the user principal name, which typically (but not always depending on how your AD is set up) is the user's email address. To simplify dynamic security based on the user identity, DAX introduces a new USERPRINCIPALNAME() function that can help you secure on a column that has the user principal name. This avoids having to use an OR filter to support both deployment scenarios. Notice that if your computer is not joined to a domain, both USERNAME() and USERPRINCIPALNAME() return the same thing (domain\login).

  • Configuring Power BI Embedded

    August 16, 2016 / No Comments » / 2374 Views

    There is a lot of interest surrounding Power BI Embedded from organizations looking for cost-effective ways to embed customer-facing (external) reports in custom apps. And there will be even more interest now that Microsoft reduced the Power BI Embedded cost dramatically by switching from per-render to a session-based pricing model. The best way to get started with Power BI Embedded is with the Microsoft sample app, which is well documented here. Here are a few notes for a better configuration experience: Register a native Azure app even if your custom app is web-based. That's because the ProvisionSample console app (inside the sample solution) expects to be configured in Azure as a native app. Instead of using the Azure Portal, the easiest way to register the app is to go to http://dev.powerbi.com/apps. On the registration page, specify app name (it should typically correspond to your web app name although you can...
