Range Start and Range End are set in the background when you run power BI. The two parameters that need setting up for incremental loading are RangeStart, RangeEnd Go to transform data to get to the power Query Editor (You can either be in desktop or creating a dataflow in Service) Set up incremental Refresh in Power Query Editor.
