Note:
You cannot delete an attribute in the following scenarios:
If the attribute is associated with a filter template.
If the attribute is used in a database-based import.
If the attribute is used in a campaign strategy, rule, or agent script.
If an attribute is marked as private, a user from that organization can delete the attribute when no other organization uses the attribute.
