Unable to Add Data Destination in Dataflow Gen 2

Hi Anonymous 

Thanks for using Microsoft Fabric Community.

Apologies for the inconvenience.

Unfortunately, you cannot directly select a data destination when the entity type is loading (I can see the same in the image that you have provided) in the query settings for Dataflow Gen2 in Fabric. This is because the loading process is crucial for schema inference and data validation, and the data destination needs to be defined later, after the schema is known.

By following the below steps, you can use to achieve your desired outcome:

1. Wait for the entity type to fully load.
2. Once the entity type is fully loaded, you will see the "Output destination" button become available in the Query settings pane.
3. Click on the button and select the desired data destination for your query.

I hope this helps. If the issue stills persists or if you have any further questions please do let us know. Glad to help.

Thanks
