System-defined fields appear in almost every inventory. Inventory system administrators can turn off display of some of these fields by opting to "hide" them, however, these fields can never be deleted from the inventory system.
The system-defined fields are as follows:
Serial number
Location notes
Internal owner
Internal responsible person
External owner
External responsible person
Maintenance contract
Purchase date
Comments
Room
Building
Department
Active use
Note that the Building and Department fields use a name look-up tool also known as a dynamic list display.
