Dataflows data types parity with Power Query
Dataflows should have parity with Power Query when it comes to data types.
Currently, dates are converted to datetime and fixed decimal numbers are converted to decimal numbers. Time does not work at all.
I haven't tested all other data types, so I don't know if these three types (date, time, fixed decimal number) are all we need.

I was trying to develop a dataflow that returns a table with columns containing records or lists. You need to convert these complex types to text by encoding them. This is way too cumbersome.

Much needed, especially date is needed. After referencing a entity in another dataflow or in pbi desktop it converts back to datetime..

@Anonymous the data type parity issue is not fixed, as far as I'm aware. So you get DateTime instead of Date at the moment.
What I referred to on the Issues website was the locale issue: there were errors when using US/Rest of the world date formats (MDY vs DMY). Here is the link for anyone curious: https://community.powerbi.com/t5/Issues/Dataflows-sets-data-types-incorrectly/idi-p/575824

@Danill, it seems I'm still experiencing the wrong Date type issue - a field appears to be correct Date type field in Data Flow, however, when loaded the data flow into PBI Desktop, such filed becomes DateTime field (12:00:00.00 is automatically added).
I read through your previous post regarding to this issue and the status was "fixed".

Time has since been partially fixed -- now it is converted to DateTime.
