Azure SQL Data warehouse - Direct Query

[SivaMani]

I created a new report in Azure SQL Data Warehouse Direct query mode. I'm getting the following error,

My report doesn't have a single data. But it shows the error. Wondering why?

@SivaMani,

Open the Query Editor and go through each step of the query to troubleshoot this problem.

@v-chuncz-msft,

I can see only two steps,

1. Source

2. Navigation

I don't have any custom column in the query.

@SivaMani,

Then do research into the Advanced Editor.
