Data Migration for Prepayment. How to handle status of prepayment invoice?

Summary:

We need to do a data conversion of open payables transactions. Prepayments are also a part of this activity. We will be taking all unapplied prepayment invoices from the legacy. These invoices will be paid from legacy. In fusion it will be in unpaid attaus and we will have to make payments so that these invoices are available for application to supplier final invoices. The problem statement is that paying this invoices would amout to duplicate payments in fusion.

I have gone through various discussion threads on this issue and one of the option is to make a payment through a dummy bank account.
