On the Import History Web UI you can display all transports that have been imported into a particular system for a specific time interval together with their return codes.
The default time interval is the previous week. You can change the interval as you need.
You can expand the transport node to display the objects that belong to the transport.
You can switch to Analysis Mode to check if objects have been downgraded by objects in transports which have been imported later, but have an earlier export time stamp. For more information, see Using Analysis Mode in Import History Web UI.
