The system requires that payment selections and the supplier invoices contained in them have the same bank account number and payment format. When you change the account and format details on a payment selection, the system automatically replaces the original details on the Financial Info tab of the supplier invoices with the new payment information.

When a supplier invoice is part-paid from multiple accounts, the Financial Info tab displays a separate line for each account and format combination that is being used. When you create a payment selection for this supplier and retrieve this invoice for inclusion in the payment, the system retrieves only that part of the invoice payment that matches the format you choose for the selection. Therefore, when you change this account and format, the system replaces only this line on the Financial Info tab of the original invoice with the new account and format details.
