Documentation for EBS Oracle Payables 12.1.3 - outside payments

I need to research and test a new process that is not included in our implementation documentation from our install of EBS Oracle Payables R12, and I'm having some trouble finding what I need in the Payables implementation guide regarding disbursements. Can anyone point me in the direction of documentation that is a bit more layperson friendly?

We are trying to implement a virtual card payment process that generates a CSV payment instruction file at the end of the payment process instead of checks, which we can then upload manually through the bank's website. The file needs to include: Payment request number, payment file date, payment total (for the file), Supplier number, supplier name, supplier email, payment instruction expiration date, payment number, invoice number, and invoice amount.
