Not all resources are displayed when issuing the command:resdef - list lastused(12/11/2017)
Note: Today's date is Dec 11, 2017
Component: ESP Workload Automation
Release: ALL
If the time is not specified on LASTUSED option, it will be defaulted to 00:00. So if one resource has been used later, then it will not show up.
So the following should be issued:RESDEF - LIST LASTUSED(NOW)
