The Power Query/Flow integration is still in Preview and I found a few things didn’t work reliably: for example the first few times I ran my Flow I got errors saying that it couldn’t connect to the Azure SQL Database, even though it clearly could while I was designing the query, but that error went away after a while. What’s more it only works for SQL Server data sources right now and I really hope that it is enabled for all the other data sources that Power Query can connect to, especially Excel. These are just teething troubles though, and it’s clear that this is going to be revolutionary for Power Query and Flow users alike!
