Incremental update on Power BI Service

Hi ThalesFerraz,

Update in Power Bi service, usually we import the date in desktop then publish it to service, create a refresh schedule by gateway.

If you update to Power BI in import model, the incremental updating is unsupported. There is a similar idea, you can vote it and improve Power BI in One Query and make this feature comes sooner. But you can load the date in two query(old and new), then union them togerther, more details, please review: Incremental Load in Power BI using DAX UNION.

You can use Direct model-no data is imported or copied into Power BI Desktop, you’re always viewing current data. But there are some limitations, please see: Azure SQL Database with DirectQuery and Use DirectQuery in Power BI Desktop. 

Best Regards,
Angelia
