Crystal Reports: Requirements Traceability Report - see no custom fields

Hi, I'm customizing some reports via Crystal Reports and really need to utilize the Requirements Traceability Report, found under Test Management.  I notice that when I open it up (in Crystal Reports- I'm using ALMComplete Enterprise), there is no "View_CustomFieldNames" under "Database Fields" section (as in other reports) visible in the Field Explorer.  I need to pull some of these custom fields into the report.  How can I do this?  I r-clicked on "Database Fields/Database Expert and it's not listed in Data/More Data Sources/Access/Excel (DAO).
