Power BI bolsters Azure AS compatibility with EffectiveUserName support

We are announcing support for user impersonation using the EffectiveUserName connection-string property. This is truly exciting because it opens the door for mass migrations of tabular Analysis Services solutions that rely on EffectiveUserName-based impersonation to Power BI. It also opens new options for administrative tools and scripts to connect to datasets on Power BI Premium using different user identities! Impersonating another user can be as easy as specifying that user’s UPN on the connection string.

New authentication option facilitates AAS migrations to Power BI Premium at a low price point

We are excited to announce that XMLA endpoints on Premium Per User (PPU) now support Azure Active Directory (AAD) authentication with service principals. This authentication option enables administrative applications to perform automated maintenance tasks and unattended service-level operations by using their own app identities, which is often a requirement for migration of existing tabular data models from Azure Analysis Services and SQL Server Analysis Services to Power BI Premium. For technical details, see the article Automate Premium workspace and dataset tasks with service principals in the product documentation.

Announcing the public preview of Power BI REST API support for DAX Queries

We are very excited to announce the public preview of a new REST API to query datasets in Power BI by using Data Analysis Expressions (DAX). Among other things, this new DAX REST API helps to address customer feedback concerning programmatic access to the data in a dataset (for example, the idea REST API access to READ datasets with almost 500 votes by the time of this announcement). The new DAX REST API avoids dependencies on Analysis Services client libraries, requires no connection to XMLA endpoints, and works in Power BI Premium as well as in Power BI shared capacity
