BPA Released Amount not updated

Hi All,

we are in R12.1.3, I created a PO referring to BPA.

BPA Release amount : 0

PO with 1 line and PO Qty : 100

Price : 1

Amount : 100

Approve the PO, Now I can see that in BPA that Release Amount increased to 100 form 0.

now I have received Qty : 60 and invoiced. Now I came to know that Supplier is not going to send rest of the amount in future. I want to Finally close this PO but when I close the PO, Pending amount ( 40 ) is not getting updated in BPA Release amount. I am expecting BPA release amount should reduce from 100 to 60 since we received and invoiced only for amount 60.
