Browse Tables hangs - Advanced Database Schema

Error:

I cannot browse the tables because our system is so large it times
out. Also, it does not let me type anything into the query field;
therefore, how does it know the table does not exist? Is there another
step in this step to show the table?

Cause:

The query that is used to display the tables in the UI takes a long time to complete, which may exceed the timeout of the browser.

Workaround:

We have recognized this as a known issue on our end which is currently scheduled for resolution in a future release. You have a few workaround options:

1) Click "Browse Tables" and wait for a while until the next screen appears
2) Create a user in the database which has access to only the tables that you need. This will minimize the query time allowing you to browse only the necessary tables
3) Create a view within the database that has your header/detail relationship and create a Database Schema (not advanced) with this view.
