This requirement has come up a few times now. Consider the following scenario:
1.) A Resource requires Equipment
2.) The Resource is Scheduled to be taken somewhere off-site
3.) The User returns from the Service Appointment, but the Equipment needs to go in for Maintenance or repair.
In this scenario, once the Service Activity is completed, the Equipment is listed as being available for Scheduling, even though the Equipment is physically unavailable.
It would be great if you had the ability to Check-out/Check-in Equipment so that it can be removed from the Resource Group until it is checked back in. Currently, you can not even Deactivate a Facility/Equipment record.
