How to use Supplier Site on Payment Request FBDI?

Hello,

We are trying to submit an invoice via Payment Request FBDI to offset a misapplied credit taken in the Expense module. We are entering the address on the FBDI that matches the Remit Site of the credit. When the invoice is created, it adds a different Party Site and not the Remit Site defined in the Supplier Module (that was used on the credit).

When we run the PPR, we are expecting the misapplied credit and recently created invoice to process together and off-set each other. However, this is not happening and believe that the Party Site is preventing this from happening.
