With the february release of Power BI the pro version support incremental loading of data. This could be really usefull in relationship with Dynamics 365 Business Central as this would make it possible to only load new or changed data reducing the load time and hardware utilisation in general.

For this to work really well we need a inserted/modified date/time field on all records in the system. Or at least on the most relevant records for reports (Sales invoice lines, G/L lines, Items, etc).

Else each partner need to add these fields as extensions to provide the customers with this option. I would be better to have it in the standard product.
