The information presented in this session will be applicable to all places where Power Query is found.

This session will begin with a quick primer on developing Azure functions and then quickly move into using Azure functions to call the Power BI REST API.

Most Dataverse implementations, whether they be Power Apps or Dynamics 365 CE on the front-end, contain amazingly valuable data for the end-users and for the organizations' leadership. Although Direct Query is one way to connect Power BI to Dataverse, enterprise deployments will benefit from using Synapse Link feature which is far more appropriate for larger data volumes. Learn the surprising options and best practices (and potential pitfalls) of connecting Power BI with Dataverse though Synapse Server.

This Dev Camp session teaches developers how to leverage Power BI embedding features for report authoring and customization. Campers will learn how to create a self-service authoring experience using the Power BI report designer by embedding reports in edit mode. Campers will also learn how to program the Power BI JavaScript Authoring API to automate the process of adding pages and visuals to an existing report. Along the way, this session will also explore other report customization techniques such as using custom bookmarks, custom report layouts, and custom report themes.

The Power BI Service has introduced a new feature known as service principal profiles which adds a powerful new dimension for scaling multi-tenant applications which use App-Owns-Data embedding. The good news here is that developers no longer have to worry about the 1000 workspace limitation per service principal. Now it's possible to develop a multi-tenant application with a single service principal that can scale far above the previous 1000 workspace limit. This session will introduce the fundamental concepts and terminology associated with service principal profiles and demonstrate how to create and manage service principal profiles using the Power BI REST API and the Power BI .NET SDK. Campers will learn the benefits of designing a multi-tenant application which creates a new service principal profile for each new customer tenant.

This session examines using the Power BI Admin APIs to automate Power BI administrative tasks and to enforce governance in a Power BI environment. Ted will be joined by Power BI Senior Program Manager, Rick Xu, as they discuss common usage scenarios for the Power BI Admin APIs such as generating a tenant-wide inventory report of workspaces and the Power BI artifacts they contain. This session will demonstrate using the Admin APIs to answer essential governance questions about which users have access to specific reports or dashboards. Campers will also learn to detect when a report has become overshared or made accessible over the public Internet using the Publish to Web feature. The session also discusses when to use the GetGroupsAsAdmin API versus when to use the Scan Workspace API. Campers will learn about the asynchronous programming required to use the Scan Workspace API. Along the way campers will also learn how to call Admin API operations which return continuation tokens such as GetUserArtifactAccessAsAdmin and the GetActivityEvents API which can be used to extract usage data from the Power BI activity log.

This camp sessions explores how to implement custom security policies in Power BI reports by designing Power BI datasets using Row Level Security (RLS). The session will begin with a quick review of creating RLS roles in Power BI Desktop and writing DAX expressions for RLS rules. The session will demonstrate common design patterns in the Power BI community for static RLS and dynamic RLS. Along the way, campers will learn how to integrate RLS security features when developing with App-Owns-Data embedding by writing RLS rule expressions which inspect the UserName and CustomData properties passed by the developer in an embed token.

This session teaches teaches campers how to build Power Platform solutions with flows and canvas apps that call the Power BI REST APIs.

This deep dive session teaches campers how to use deployment pipelines for managing the application lifecycle of datasets and reports and for enabling CI/CD in a Power BI environment. The session explains how deployment pipelines are configured to create dedicated workspaces for developing and testing Power BI artifacts including datasets, reports, dashboards and dataflows. The session will demonstrate how to deploy artifacts in a deployment pipeline from the Dev workspace to the Testing workspace and then to the Production workspace where updates are made available to all users. Along the way, campers will learn how to configure data source rules, to automate pipelines deployment using PowerShell and the Power BI REST API and to integrate deployment pipelines together with Azure DevOps pipelines.

In this camp session, Scott Sewel of the Power BI CAT team will demonstrate the value that Power BI brings to the Power Platform, specifically working with Dataverse, PowerApps and Dynamics 365 CE. The session will examine the different options for connecting from Power BI to the Dataverse and discuss the strengths, features, and limitations of each of these options. The sessions will look at how to implement a report in Dataverse as a general Dashboard – or as a filtered report on a record for powerful contextual reporting.

This camp session focuses on developing with Power BI embedding techniques in a Salesforce environment. The session will explain how to implement User-Owns-Data embedding in Salesforce using a Single Page Application (SPA) with client-side JavaScript code written to acquire access tokens from Azure AD and program against the Power BI JavaScript API. The session also covers the more challenging task of implementing App-Owns-Data embedding in a Salesforce requirement which involves creating an Apex class which runs in the Salesforce cloud and calls to the Power BI Service under the identity of a service principal. Campers will also learn how to develop Lighting Aura components and Lightning web components which surface embedded reports on pages in a Salesforce environment.

Power BI provides Internationalization and localization features which make it possible to build multi-language reports. For example, you can design a Power BI report that renders in English for some users while rendering in Spanish, French, German or Dutch for other users. While Power BI provides all the features required to design and implement multi-language reports, the path to success is tricky and not intuitive. The purpose of this Dev Camp session is to explain how to use the Power BI features for Internationalization and localization from the ground up and to provide the guidance for building reports that support multiple languages. If a company or organization has the requirement of building Power BI reports that support multiple languages, it's no longer necessary to clone and maintain a separate PBIX project file for each language. Instead, they can increase reuse and lower report maintenance by designing and implementing multi-language reports.

This session will introduce campers to the App-Owns-Data Starter Kit which is a sample solution for developers built using .NET 5 to provide guidance for organizations and ISVs who are using App-Owns-Data embedding with Power BI in a multi-tenant environment. Camper will learn how to write C# code to onboard new customer tenants by using the Power BI REST API to create Power BI workspaces, assign workspaces to capacities, import PBIX files, patch datasource credentials and start dataset refresh operations. The session will also explain how to implement a custom authorization scheme where different users can be assigned to customer tenants with only viewing permissions or with edit and create permissions. Along the way, campers will also learn how to implement a custom telemetry layer to log and monitor user actions such as viewing, editing creating and copying reports and to capture and monitor the performance of loading and rendering reports.
