Power BI

You can’t create a new table with the same name as an existing
query or item in the model.

The “New Table” button creates a new table named “Table”

This means if you create a query named “Table”, the UI cannot
create any new tables. It’s before the rename step.

I discovered this also includes the names of disable queries.
At first I thought It was a cache—issue, but it’s not.

This is actually a good “bug”.
Which is better than if the opposite was true — letting you
create tables and expressions with ambiguous identifiers.
