Problems in Data Warehousing

Should Backdated Transactions Change Values in the Data Warehouse?

Due to poor operating practices, a company sometimes has to backdate transactions.  These transactions are entered a month or more after they actually occurred.  The people in accounting argue that the “historic” information should not change.  The standard in the data warehouse transformation process is this: if a transaction has a date that is 40 days old, the data warehouse data for that day will change.  Should a backdated transaction not change the “historic” information in the data warehouse?
