Can change the payment date after PPR is submitted?

Dear Guys,

I'm studying the PPR of R12.1.3. A question after below steps.

1.  Created a PPR and 102015 as the payment date.

2.  Submitted the PPR and select some invoices to pay.

3.  Built the payment.

4.  Formatted the payment.

...Now waiting the bank statement from bank.

5.  On 17-MAY-2015, got the bank statement, finance want the payment to be 17-MAY-2015 instead the initial PPR payment date(10-MAY-2015).

How can PPR do it?
