Reports
There are a number of 
SMP 
Reports pre-installed but you can also create your own.
I thought it might be helpful to document how to create Reports to get the most common information people require, this could be an Asset's Status, it's Location, Department, Inventory data etc. Sometimes the joins aren't obvious or you find a Report with some information but not all and you need to merge the two.
- Asset User Owners
- Asset Department Owners
- Asset's Status
- Asset's Location
- Asset Info
- Department's Location
ToDo
- Inventory (AeX ...)
- Disk Space
- Last Check In Date
Please add links to any useful Reports you've found or made.
Please comment below for any Reports you'd like adding to the list.
SSE
I would advise adding the SSE Reports provided by 
Symantec, these are useful for any Support Cases you raise.
