Starting with the release of Strategy ONE (March 2024), dossiers are also known as dashboards.
This feature supports more Big Data scenarios where moving large amounts of data to memory is not practical. Time-derived columns such as “Month of timestamp” or “Day of timestamp” and other out of the box time-based derived attributes are now calculated at the source. This feature also supports multiple attribute forms.

To implement this behavior in your dossier, enable the feature flag. For details, see KB442250: Always calculate derived attribute at source for Live Intelligent Cube datasets.
