Is incremental refresh available with custom connectors?
On reports with tables from a custom connector, I’m getting Error 500 – Internal Server Error while uploading the report to Power BI Service, if incremental refresh is also enabled. As far I can tell...
After some back and forth with the Microsoft support and product teams, the incremental refresh feature is now working with custom connectors. I've tested with the Power BI Desktop (July 2020), the On-premisses data gateway 3000.51.7 (July 2020) and the current version of the service (Service version13.0.14066.71).
There's only an additional step. After setting up the incremental refresh and uploading the report to the service, one must go to the data set settings and select "Discover Data sources". After that, the incremental refresh, through the connector, works as expected.
