In my previous post "Power BI Embedded, Service Principals, and SSAS", I discussed how you can integrate Power BI Embedded (App Owns Data) configured for service principal authentication with SSAS to pass the effective user identity. One important observation is that you can use this approach with both internal and external users. For internal users, the Power BI gateway (running under an account that has…

Null and zero typically have different semantics, where null indicates an unknown or missing value while zero is an explicit value. Sometimes, however, you want to show nulls as zeros. For example, an insurance company might want to show 0 claims instead of a blank value. By default, when a DAX filter doesn't find any rows, the formula returns null (BLANK in DAX). For example,…

Service principal authentication is preferred because it doesn't require storing and using credentials of a Power BI Pro account. Configuring the service principal and embedding reports with imported data is easy. Not so much with embedding…

As the poet said, "let me count the ways". I've been amazed by the extent some organizations would go into inconveniencing their employees in the pursuit of better security while they do such dumb things. In one case, an organization would automatically log out login sessions after a certain period of inactivity, allow employees to access Power BI only on company's approved devices, and prevent…
