I am developing reporting based on our cloud deployed Business Central instance.
I attempted to load table data into my desktop PowerBI report, which was very slow & often failed to load. Working with ~300k rows per table I attempted to shift some of the processing to the cloud; I've written queries to provide aggregation to minimise the workload in PowerBI. These work perfectly in the "preview" (& indeed show all of the data required- aggregated).
When I attempt to load the same query, however, I am back to a perpetual "Creating connection in model..." load screen.
Edit: I have attempted to perform this both with the Business Central connector & the OData Feed with the same result.
Any suggestions or pointers would be greatly appreciated.
