How do I set up a sub-asset?
In Caselle Asset Management, a sub-asset is a smaller asset or component that is linked to a larger “parent” asset. Sub-assets allow organizations to track important components separately while still associating them with the main asset they belong to.
This is useful when:
- components have different useful lives,
- require separate maintenance,
- or need individual tracking for accounting or inventory purposes.
Examples of sub-assets include (Parent Asset, Sub-Asset):
- Building, HVAC System
- Fire Truck, Radio Equipment
- Computer System, Monitor, Docking Station
- Water Plant, Pumps and Generators
A sub-asset may have its own:
- asset number,
- depreciation schedule,
- maintenance history,
- location,
- or replacement cycle.
For example:
A building may last 40 years, but its roof may only last 15 years.
Tracking the roof as a sub-asset allows it to be:
- depreciated separately,
- replaced independently,
- and managed more accurately.
Add a sub-asset to a primary asset
A sub-asset is an asset that is related to another asset. A primary asset may be made up of more than one sub-asset.

Example
Joe buys a snowplow for City XYZ. He buys a truck and a snowplow to attach to the truck. City XYZ can record the asset as a "snowplow" or record the truck and snowplow as separate assets. City XYZ chooses to create an asset record for the truck and an asset record for the snowplow. When City XYZ sets up the asset record for the snowplow, they select the checkbox titled Set As Sub-asset and enter the asset number assigned to the truck as the Primary Asset Number. Now, the truck and snowplow are linked together in the asset table.
