I wondered if anyone else had come across this.
After a transform or append an automatic type conversion is added and causes rows to disappear.
The error is Complex data types and not all data is loaded.
If I remove the type conversation that was automatically added it shows all the records but as soon as I save it, it puts it back and not all the records come through.
I can see in the option for the desktop version don’t automatically convert types but not in the online version when creating dataflows.
Any advice greatly appreciated.
Many thanks
Chris
Hello - do you mean you are trying to load rows with complex types to the data model? Those should not be loaded. Can you share some screen shots?
