I am using the UWL for ESS leave request. This works fine and the HR-System is connected. But when I check the button (something like) update closed objects/items. I get the error message: "Could not verify if the backend of system <SYSTEM ALIAS> is configured for optimized delta pull."
It is the same like here: approved-items-in-uwl-remains-in-the-status-new
Did someone face the same problems and could give some hints what to do?
Thanks a lot, Vanessa
