Unique FTRs help distinguish one external inquiry from another external inquiry.
Both the input side and output side must be considered when evaluating the FTRs used by an external inquiry. Normally they are the same but there are instances where they may not be the same. The combined total should be used when evaluating an EQ. For example, a security check may be done on the input side of an external inquiry. The security check is done to make sure the user of the application has the appropriate level of authority to view the data.
