API for generating debit memo invoice through interface and apply on standard invoice.

Hi,

Want to know is there any API for generating debit memo invoice through interface and match it to standard invoice.

We are on Oracle Apps R12.1.3 version. We have a requirement where our business users asking us if there is any automated way to create the Debit Memo in AP and match it to Standard AP Invoice. I want to know if we can do it using standard AP Invoice interface or if there is any Public API available to cater this requirement.?

In case there is no API available or not doable from standard open interface, Is there any workaround available to carryout this task?
