Auditing Hierarchy Loops in Department Trees

Content

Hi Guys, 

Does anyone happen to have a report that is able to show hierarchy loops within a department tree? 

We do currently have a report that shows which managers are allocated to a particular department, but it's quite a manual process to identify a hierarchy loop within this. Usually with an org tree you would recieve the message "Unable to select manager due to a hierarchy loop" or something along those lines.

We just need to identify if managers are reporting to other managers who are on the same level. For example in the screenshot below the managers in 'Change & Release Management' & 'Technology Service Delivery' are reporting to each other, so we need a report to identify this.
