How to create Item codes for Fixed Assets

How to create Item codes for Fixed Assets. Assume I have an Item Name “Computers”, and I can create 10 Computer assets with unique Asset ID codes for them. But when creating an Item, there should be a common Item code, is there any Item code naming standard that I should follow ? I am pretty new to working with an ERP system.

Eg: Item Code = Com-02,
Asset ID = Com-02-0001

Your issue will be solved from this format.
