Since the most recent accounts receivable master file was destroyed, the operator should use yesterday's father master file to reconstruct it. This is because the father file holds the second most recent version of the master file and has already been updated with yesterday's transaction data. Processing yesterday's father file against yesterday's transaction file will ensure that all relevant transactions are included in the reconstructed master file. Processing yesterday's son file against yesterday's transaction file may result in missing transactions, as the son file only includes updates from the current day. Processing yesterday's grandfather file against yesterday's transaction file may include outdated data that has been overwritten by more recent transactions.
