Deleting fields
You can delete a field for a record type in a schema from
the Fields grid. 
Before you begin
The following restrictions
apply to deleting fields: 
- In the Rational® ClearQuest® Client, any queries that use a deleted field are no longer valid and must be edited by removing the deleted field from the query or the query must be deleted.
 - When you delete a field, the DB Column Name generated for the field (by default, the same as the field name) is retained. If you later reuse the same name to create a new field, a unique DB Column Name is generated.
 - If you explicitly refer to the name of a field in script code and then delete that field, you must also remove references to the deleted field from the script code.
 - You cannot delete a system field. In the Record Fields grid, system fields are dimmed.
 
Procedure
To delete a field:
- Start the Designer.
 - In the Schema Repository Explorer view, expand the Record Types folder in your schema and then double-click on a record type. The record type editor opens.
 - Click the Fields tab to view the Records Fields grid.
 - In the Record Fields grid, right-click the row of the field you want to delete and click Remove.
