DataFlow Gen2 with destination to Lakehouse creates strange tables

[Anonymous]

Hi to everyone

I'm a first timer with Data Factory though i'm pretty experienced with PowerBI power Query. 

So i've created a dataflow gen2 that takes data from On-prem SQL server, prepares those into tables and loads to the destination of Lakehouse. Once executed I find on lakehouse not only those tables that I've ordered to create as a result of DataFlow execution but others with crazy letter-numerical names but with contents of those other tables i've ordered to create... what goes wrong?

THanks for support

found out that all of those are having parquet word in name... probably those are technical tables that should be created? Then the question is which one should I use to create a data model (star scheme) for PowerBI report?

Hi @Anonymous ,

Can you please share screenshots like this?

Tables at my lakehouse -

When I tried to reproduce your scenario, I am able to get 3 different tables without any issue.
I just want to know what is the step that created those parquet tables.

looks like the problem was resolved by using another Lakehouse as a destination point. The new lakehouse is created by myself, while previous was created by my colleague. In  new LH the problem is not present. DataFlow Gen2 remains all the same except having another LH as a destination point. HOpe it helps you to find a bug. If I can help you somehow, I'm available.
