Supplier Employee - Trading Partner Name in PPR is different than in the Supplier Record and Expense

Hi,

We are using internet expenses and creating the supplier employees via execution of the Export Expense Report program.

The Supplier is created as 'John Smith' (Trading Partner field) for the Supplier record and in the invoice automatically created by the process the Trading Partner Name is also 'John Smith'

But we created a payment process request and after the payment is confirmed, we check in the Payment Instructions page and in the payment details it says:

Trading Partner: Smith, Mr. John

Payee: Smith, Mr. John

Why the system is assigning the employee name instead of the supplier name in the PPR?
