Attaching Scanned Supplier Invoices with the Standard Invoices in Payables. Document of Record Funct

I have a Question about the "Document of Record" Functionality in Oracle E-Business Suite. Please read the NOTE 409106.1 on "Document of Record" Functionality on Metalink

Q1. Can we use the "Document of Record Functionality" in Payables R12.1.3 to attach scanned copies of Supplier Invoices to the Invoices in Oracle Payables?

Q2. In AP Invoices -> Enter ->Invoices, There is a PaperClip Icon in the toolbar which can be used to attach the "Scanned Document" to the Payables Invoice screen? Is that the same functionality as "Document of Record" functionality?

As-Is process

Currently we are using a Third Party system (which consists of Software and Hardware) to store the scanned copies of "Supplier Invoices" outside of Oracle. We have an interface between the Oracle and the third party system. These scanned images of the "Supplier Invoices" can be accessed by the customized menu which executes the function and that function pulls the "Scanned Image" image from Third Party Hardware and displays in Oracle Payables.
