Here you can choose to Show total per cost type. This means that the costs are added up and shown as a total per cost number in the nonconformities. The total amount appears at the bottom of the list.
If you classify the list by Nonconformity number, you can also choose to Show detailed costs. All cost rows in an nonconformity will then be shown. Otherwise, the nonconformity's cost rows are only shown as a total. When classifying by nonconformity number it is also possible to include nonconformity comments in the list by selecting the Show external comments and Show internal comments options.
