Payables not applying other available prepayments up to the remaining prepayment amount

Hi,

I have Couple of Pre payments against to Supplier. we have created invoice using interface for the same supplier, and tried to apply both prepayments.

As Oracle interface will allow to store only one Pre payment, we have given oldest Prepayment to be stamped on the invoice, sum of both Prepayments in PREPAY_APPLY_AMOUNT.

Post Invoice creation i see only Amount that is there prepay_num got adjusted. Other Prepayment is completely ignored.

My expectation is: from Oracle source

"If the prepayment amount you enter exceeds the available amount on the specified prepayment, Payables then applies other available prepayments, in order of oldest to newest, up to the remaining prepayment amount."
