KFS may be configured to allow bank codes to be configured on individual documents. The system also allows an institution to post offset entries to a bank-specific account and object code (defined on the Bank Maintenance document.)
When this type of configuration is used, it changes the way the PDP interacts with payments related to the documents that make disbursements (specifically, the payment request and disbursement voucher).
Customers may also choose to specify a bank code in their XML payment files.
