Gellert, The quota used method was fixed in 5.8. It looks like the ManageIQ domain in the reproducer environment is old. Here is the fix: https://github.com/ManageIQ/manageiq-content/blob/fine/content/automate/ManageIQ/System/CommonMethods/QuotaMethods.class/__methods__/used.rb#L51 Can you test with the latest 5.8 Automate ManageIQ domain? Let me know if you have any questions. Billy
