Payment discount taken row has a Budget Status "N". How do we proceed to get a "V"?

We are implementing PS Payables 9.1 PT 8.53, Bundle 25 with Commitment Control enabled for GL, AP and PO. We entered a voucher for $1193.60 with Payment Terns 1/10 N 30.

Budget Check Valid, Approved and paid earlier to take the discount. Payment $ 1181.60. Voucher posting and Payment posting run successfully BUT we noticed the Discount row has a Budget Status "N". (see attached document with detail page shots). Is there another process we need to run to budget check the discount taken?  Research in Oracle Knowledge did not return much. Although, there was a case with an earlier release whereby one line showed a Budget status "N" and support personnel talked about "unfinalizing" the voucher and then budget checking?
