Oracle Wire Payments vs Oracle Electronic Payments

My Below Question is based on Oracle Payables Prospective because we have some suppliers to whom we have to pay by ACH (Electronic) payments

------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Currently we are having some suppliers with Electronic and some suppliers with WIRE Payments in R12. A Separated Payment process request is run for Electronic payments and a separate payment process request is run for WIRE Customers.  

Then we print the payment register for electronic payments. We log into our Bank Website and manually pay those suppliers through Bank website.

But for some reason some suppliers payments will be registered under WIRE Payment method eg: Payroll. Payroll sends a separate email to the Treasury department to pay the suppliers. Treasury department log into the bank website and manually pay those WIRE Payments. It means they are processed manually exactly like electronic payment.
