FTA CCF Groups File Overview
The FTA CCF Groups file stores the CCF groups to use in common cause analysis. It is a singular support file, which means that only one occurrence of this file type can exist in the Project.
The FTA CCF Groups file has two panes in which you enter CCF groups and specify the characteristics associated with each group. The following table describes these panes.

You need to insert CCF groups in the
FTA CCF Groups file only if you are performing common cause analysis. When you insert CCF groups in this file,
CCF Group becomes available on the
Data Source page in an event’s
Properties window so that you can select a CCF group as the parameter definition. For more information, see
Data Source Page.
When you select
CCF Group, the field to its right becomes available so that you can select a CCF group from those in the Project’s
FTA CCF Groups file. The first group in this file is selected by default. In the
System file, you can view CCF Group assignments in the
FTA CFF Table. For more information, see
Viewing and Modifying CCF Groups in the FTA CCF Table.
