Thanks for the question. In an Asset application, you have a standard Asset template that TeamDynamix provides. This is the best path to use alongside any custom attributes that will appear on the template you would use to import into TeamDynamix. We don't have any specific templates for Assets. If you are looking at loading in Configuration Items (CI) there is a separate import template you can use. Both located in the Import menu of your Assets/CI app. If you don't see it in TDNext in the Assets/CI app, check with your TeamDynamix Admins for access.
Let us know if you have any additional questions.
