You can define your own asset forms by just adding as many attributes as you need.
Please bear in mind that you can automatically create most-used attributes and assets forms by importing our built-in schemes.
Please see Creating scheme(s) which come out-of-box for details.
First, log in to JIRA, and click on AIP Menu > Forms menu item
Give a name to your form, then select all attributes that you want to be in the form. You can change sort order by just dragging.
For instance, define an asset form for "Personal Computers" for your company.
Then click Save button. You'll see that newly created 'Personal Computers' form has been created successfully.
