2. Datapoint traceability points directly to the specific predecessor record(s) and should be implemented if practical and feasible. This level of traceability can be very helpful when trying to trace a complex data manipulation path.

The BDS and OCCDS structures were designed to enable datapoint traceability back to predecessor data.
