Deleting an Attribute
* 
When an attribute is deleted from a type, all instances of that attribute throughout your Windchill system (including the attribute value) are permanently deleted from the database.
To remove an attribute from the user interface without deleting it, remove the attribute from any attribute layouts. The attribute instances are retained in the system, and the attribute can later be added back to the user interface by adding it to an attribute layout.
The Delete action or delete icon is available from the following locations:
From the tool bar of the Attributes tab.
From the right-click actions menu for an attribute on the Attributes tab (if the attribute can be deleted).
From the Actions menu of an attribute information page (if the attribute can be deleted).
Only attributes explicitly created on the type can be deleted; out-of-the-box attributes and inherited attributes cannot be deleted from a type. If an attribute is in use by another attribute or is used in any attribute layout, it cannot be deleted. If any attribute selected for deletion cannot be deleted, the entire delete action fails. A message indicating the reasons for failure displays.
To delete an attribute from a type, use the following procedure:
1. Select Edit from the Actions menu for the type to enter edit mode.
2. Perform the delete in one of the following ways:
From the Attributes tab, select the attribute that you want to delete, and click the delete icon .
Right-click on the attribute on the Attributes tab, and select Delete.
On the attribute information page, select Delete from the Actions menu for the attribute.
A warning message appears asking you to confirm the deletion.
3. Click Done to save the change and return to view mode, or click Save to save the changes and remain in edit mode.
