I ran into this behavior in my Denodo Scheduler Administration tool previously because I was using an older Denodo Platform update in my machine.
To overcome this I suggest you go for the latest Denodo Platform update available on the support site.
In addition to this, I will also ask you to check if the detail reports in the project “admin” are deleted by someone in your team. This might also cause the detail reports link to not appear.
I would suggest you keep in mind of these scenarios before trying to access the detailed report in Denodo Scheduler Administration Tool.
Hope this helps you!
