by deleting from the Attributes Window. The Write role should be mapped to your User
Group.
Highlight the Attribute Definition and click the Menu
button.
Click the Delete button.
The Attribute Definition is deleted after confirmation.
Note:
You
cannot delete a definition if any dependency like Attribute, Hierarchy or
Filter is attached to it. Detach the dependency before deleting the
definition
