I have two queries from Azure SQL Server, with "DirectQuery" mode.
Now I created two reference queries based on that 2 queries; and then merge the two refernece refernece queries. In the Merge window, I selected 7 columns from both queries, and then the data table shows expected merged data.
But when I click "close and apply", it says "Mixing DirectQuery and imported data is not supported."
I confirmed that all of my original queries are "DirectQuery " - so what does the error message complaint about?
