Hi
I am using Dataflow for the very first time. I have copied over 7 tables, wth steps from power bi desktop. However when I refresh the data flow I receive the following error
Error Code: 104203, Error Details: Couldn't refresh the entity because of an internal error
I have 7 tables and 6 out of 7 seem to successfully refresh.
Can anyone suggest what I do next
thank you
Richard
Hi thank you for your quick response . I have checked the advanced query editor and there are no errors.

Check the m query of that table from the advanced query editor. That might tell you at which step the process is failing.
