Attention: You should be extremely cautious when purging transaction information. Once you commit the process, Oracle Inventory removes all related information from the database. You cannot view or report on this information once you purge it. For example, you can no longer report purged information with the Accrual Reconciliation Report, the Transaction Register, and so on.
Warning: Since the Job/Lot Composition functionality in Oracle Work in Process depends on the material transaction history, you should not enter a purge date which purges material transactions that are part of a genealogy you want to retain. See: Viewing Job Lot Composition and the Job Lot Composition Report.
