Inactivating requirement types
Inactivate a requirement type if you do not want users to select it when adding new requirements or changing types on existing requirements. Requirements using the inactivated type are not updated and continue to use the type unless it is changed later. You can activate the type if you decide to use it again.
1. Choose Tools > Administration > Requirement Types.
The Configure Requirement Types dialog box opens.
2. Select a type and click Inactivate.
The type is inactivated.
Note: Inactive requirement types are displayed in gray. To activate an inactive type, select it and click Activate.
