A feature that I love in Power Query across Excel, Power BI Desktop, and Visual Studio, is that I can copy a query from one, paste it into the other, and all that queries dependencies will also get imported automatically, which might include:
- Other queries (think Append or Combine)
- Parameters (think API parameters, cloud file paths)
- Functions (think API call or a whole set of transformations)
With a single copy/paste action I might copy 12 different objects without having to even know about the underlying query dependencies.
I don't see any part of the Dataflow PQO experience where I could paste a query from the desktop tools. I don't think the workflow above is currently supported in the browser, but just in case, did I miss it? Right-clicking on the white space of the left pane in Edit Queries in PQO (my best guess as to where it would make sense that it works) doesn't show Paste (after copying a query from PQ in PBI Desktop):
Otherwise, will this be supported? It is fairly tedious and error-prone to have to recreate everything from blank queries.
Also, parameters and functions are not yet in PQO, are they?
EDIT: I posted this request, vote if you're interested!

I'm not familiar with Dataflow PQO, in power bi desktop or Excel, it could be achieved.
and for Dataflow PQO you may submit the post to there.

You can use Get-Data and then choose blank query. There you can paste the M script from Power BI Desktop.
Another alternative is edit an existing M script by clicking on the right button on a query then choose 'Advanced editor'.
Hope that it helps.

@yaronc I know, I mentioned starting from a blank query in my post. As I said that's not nearly as efficient as done a single copy/paste to get all dependencies imported in one swoop.

@otravers, finally got around to testing Dataflows. Pasted this simple dynamic EndDate parameter from Power BI to a blank query:
let Source = #datetime(Date.Year(Date.AddDays(DateTime.LocalNow(),-1)), Date.Month(Date.AddDays(DateTime.LocalNow(),-1)), Date.Day(Date.AddDays(DateTime.LocalNow(),-1)), 23, 59, 59) in Source
and Dataflow insists on converting to a table before considering it "valid". Anyone know a workaround?

@musicbydannyd right click the name of the parameter in the PQO editor and uncheck Enable load before saving it, and this will no longer happen. Same thing with functions. They're both supported but not yet fully handled by the UI.

@otravers, that did the trick! Makes sense now, given loaded queries are converted to csv in Azure Gen 2...
Thanks so much, DannyD
