The Transaction Number (also known as the AUS Transaction Number) is a randomly generated number that is assigned to a specific Loan Product Advisor submission. For example, if an individual Mortgage is submitted to Loan Product Advisor five times, the same Key Number will be used, but each submission will generate a different Transaction Number.
