External pricing is applicable for a transaction if ‘External pricing applicable flag’ is checked in Source Network Preferences (PMDSORNW).The price request is sent to the external pricing system which is linked in Host parameters as a request through JMS queue. The charge/tax received in the response message is applied to the pricing components applicable for the transaction.

For Manually Initiated Transactions, enrich button will skip Internal pricing pick-up and the necessary pricing values are fetched from the external pricing system as part of processing after Authorization. For Transactions from Upload Channels, necessary pricing values are fetched from the external pricing system during STP Processing.

Transactions are moved to External Pricing Exception Queue if the following exceptions are encountered during external price fetching:
