Is there a list of Power Query M steps that are supported in dataflows?
At the current time Dataflows seemed enfeebled by what is possible via the web interface.
I am trying to add a date column from a Julian date field in my data to a computed enitiy in the dataflow
#"Added Custom" = Table.AddColumn(Source, "Updated", each Date.AddDays(Date.From(DateTimeZone.From("20" & Text.Start(Number.ToText([IMUPMJ]),2) & "-01-01")),Int64.From(Text.End(Number.ToText([IMUPMJ]),3))))
but end up with "column with a complex type" warning that stops the data loading, with the "something went wrong" meesage.
Does anyone know if there is a documented list of Power Query M steps that are supported in dataflows
Here is a blog Get the most out of Power Query in Power BI Dataflows which may help you.
