The asset class is the main class to classify assets. Every asset must be assigned to only one asset class. Example of asset class is Furniture & Fixtures, Plant & Machinery, and Computers etc. The asset class also contains G1 account, when any asset is procured, G1 account is debited. Whenever you create and asset master, it becomes mandatory to mention the assest class for which you are creating the required assets. So, whenever any asset transaction occurs, the G1 account attached to the asset class is automatically picked up and the entry is passed. You can also specify the default values for calculating the depreciation values and other master data in each asset class.
