Hello,
A resource association is a link between two resources, such as between a user and a computer. The user of a computer has an association with that computer, and vice versa.
Whenever new custom association gets creates, by default it indicates name as ‘New Editable Association Type’
New Editable Association Type association type will be present (if created) in the:
Settings --- All settings – Settings ---- Service and Asset Management ---- Resource and Data Class Settings ----- Resource Associations
Or
Settings> All settings >Settings > Notification Server > Resource and Data Class Settings > Resource Associations
User (which is having permission to delete) can delete only custom resource association using delete option present in the context menu\right click menu.
I hope that this answer will help you in resolving your query.
Thanks,
