This invention relates generally to multi-currency production ledgers, and more particularly to methods of converting multi-currency production ledgers to accommodate the unification of several national currencies by respective participating states into a single currency. In particular the invention relates to a method for use with a computer for converting an ongoing old corp production ledger processing with a participating currency, to an ongoing production ledger processing with a target currency, the old corp production ledger comprising an old master file including a plurality of old master file records, each old master file record comprising a key identifying the record, data fields and amount fields, wherein the conversion is accomplished by selecting a target currency, selecting a particular time period, creating a target currency master file that is substantially identical to the old currency master file, by creating a target currency corp record corresponding to each old currency master file corp record within the old currency master file except that the target currency corp records within the target master file hold zero balances and all participating transaction currency records and their book one equivalents within one old master file key are replaced by a single target transaction record and its book one equivalent, converting the amounts of all transaction currency records and their book one equivalents for the selected time period into their corresponding target currency equivalent amounts, rounding the target currency equivalent amounts, and populating the target currency corp records within the target master file with the corresponding rounded target currency equivalent amounts. |
