Dataflow running late

Hi brunoctesser ,

Thank you for reaching out to the Microsoft Fabric community.

We have verified that everything is set up correctly, but you are still encountering the issue. Before raising a ticket, could you please check the following method.  If the issue persists, you may proceed with raising a ticket as mentioned uzuntasgokberk .

Another option to consider, if you need all that data, is to use direct query for dataflows.

Using DirectQuery with dataflows - Power BI | Microsoft Learn.

Aggregations in Power BI can improve query performance over large DirectQuery semantic models. By using aggregations, you cache data at the aggregated level in-memory. 

User-defined aggregations - Power BI | Microsoft Learn

Note:  That this functionality is available only with premium or premium per user, as it requires enabling the 'Enhanced compute engine settings' for the Dataflow.

We have mentioned the link below, which is like your issue and provides better clarity. Please check it once.
