Control Total


A value that can be compared against the sum of a batch of items to check against loss in transit. Similar to old-style test keys, the system can compare what the control total indicates was transmitted with the incoming records of what was actually received. If the control total is transmitted separately from the transactional message(s) to which it relates, it can provide some protection against fraudulent or mischievous manipulation of data in transit. The safest way of using control totals is to send the control total message at a different time, and by a different route to the master message.
