Microsoft has introduced a preview of calculated columns for Direct Lake semantic models in Power BI, a feature that was previously a significant limitation. This update allows users to write DAX calculated columns directly within Direct Lake models, which are then materialized during metadata refreshes. While this enables common patterns like concatenated display columns and conditional categorizations, it still does not support calculated columns referencing measures or MDX-based hierarchies. AI
IMPACT Enables more complex data modeling within Power BI's Direct Lake mode, potentially improving user experience and data analysis capabilities.
RANK_REASON This is a feature update to an existing product, not a new frontier model release or significant industry event.
