This session shows how to design user-context-aware calculated columns in Power BI using the Expression Context property and DAX functions such as USERCULTURE(), USERPRINCIPALNAME(), USERNAME(), USEROBJECTID(), and CUSTOMDATA(). We will walk through practical personalization and translation scenarios across supported storage modes, including Direct Lake on OneLake, Import, and DirectQuery. The session also clarifies when calculated columns are evaluated, how materialized versus unmaterialized behavior affects refresh and query performance.

Preview feature session; content may evolve as product updates roll out. Preferred duration 60 minutes. Technical prerequisites: working knowledge of DAX and semantic modeling.
