Explain the importance of asset classes. Give examples?

The asset class is the main criterion for classifying assets. Every asset
must be assigned to only one asset class. Examples of asset class are
Plant& Machinery, Furniture & Fixtures, Computers etc. The asset class
also contains the Gl accounts which are debited when any asset is
procured. It also contains the gl accounts for depreciation calculation,
scrapping etc

Whenever you create an asset master you need to mention the asset
class for which you are creating the required asset. In this manner
whenever any asset transaction happens the gl accounts attached to the
asset class is automatically picked up and the entry passed.

You can also specify certain control parameters and default values for
depreciation calculation and other master data in each asset class.
