The new Adjust transaction is used to adjust the purchase amount downward after the original Sale. The trigger for the new Adjust transaction is the <OriginalAuthorized> amount tag. If an Adjust (or AdjustByRecordNo) transaction includes the <OriginalAuthorized> amount and the total amount is less than the original authorized amount, then the new TSYS Adjustment transaction is performed to adjust the transaction amount downward. Without the <OriginalAuthorized> amount tag, an Adjust transaction will simply adjust the TIP amount as for previous releases.
