Hi.
Is it possible to get more details about the "unexpected error" when creating dataflow ?
I try to create new dataflow, but as soon as I add more than one datasource in power query, I keep getting this error and I have no idea why - the message is not very specific.
Hi @sartys ,
According to my test, by entering the correct connection credentials, I successfully connected to the database data source. Can you provide detailed connection steps so that I can help you find the problem.
Let me know immediately, looking forward to your reply.
Best Regards,
Henry
