1. A method of correcting a data field that is repeated in a plurality of records in a trade compliance system, without having to repetitively enter a correction in each instance of the data field, the method comprising: making a copy of the plurality of records in which the data field is repeated; modifying the copy of the records by performing a global edit that makes an identical correction in each repetition of the data field, without redundant data entry; and uploading the edited copy of the records into a database of the trade compliance system, thereby updating the records while preserving existing data that was contained within the repeated data field prior to the global edit.
