Aggregation Precedence in Power BI: How does Power BI choose between candidate aggregation tables with the same Precedence?
Precedence is one of the aggregation properties that you can define on an aggregation table in Power BI. In a model with multiple aggregation tables, you can use Precedence to define the order in which aggregation tables will be considered by Power BI to answer queries. The higher the Precedence number, the sooner the aggregation … Continue reading Aggregation Precedence in Power BI: How does Power BI choose between candidate aggregation tables with the same Precedence?
