How and where can I check the split of amount for Direct debits

Summary:

We have a requirement where in for Direct Debit (DD) invoices invoice template should print the amount that is due.

Eg: If a invoice have a due date of NET 30 Days, with invoice amount as 1000 which is recurring on a monthly basis on each month 100 should be debited from customer account. I expect this split should be part of ar_payment_schedule table so that on monthly basis it is recognized that amount should be debited from customer account. But I see over all amount in ar_payment_schedules as 1000 and not the split. Where can I get that information?
