Charge computation for HKFPS payment transaction is made based on the “External Pricing Applicable” flag set at Source Network Preferences level.

If External pricing is not applicable for the Source and Network combination, then Charge and tax for HKFPS Payment transaction is calculated based on the Pricing Code linked in the outbound credit transfer payment preferences (PKDOCTPF).

Pricing components applicable to the price code and the attributes like whether the component is a charge or tax, Pricing currency and the exchange rate type are derived from Pricing Code maintenance (PPDCDMNT).

For the payment source of the transaction and applicable service model of debit customer, pricing values are fetched from Pricing Value Maintenance (PPDVLMNT).

The pricing value record valid for current date only is considered. Any pricing value record maintained with a future effective date is excluded.

Charge components are processed prior to tax components involved. If a charge component is waived, the related tax also is waived automatically.

If “External Pricing Applicable” flag is set as Yes at Source Network Preferences, charge calculation is skipped and system captures the pricing details from External Pricing System.

If the pricing check response status is 'Interim' or 'Rejected', then transaction is rejected with proper error code.
