Hello,
I am also having an issue on that part of BAS Superbadge, which the following error message:
Challenge Not yet complete... here's what's wrong: 
The 'Accounts by Market' report does not show the coThe 'Accounts by Market' report does not show the correct level of detail

     

 I have checked the requirements and I cannot understand what the issue is. Any advice would be much appreciated!

Thanx
