How to disable late payment charges for an invoice

Content (please ensure you mask any confidential information):

I had an AR invoice for which customer had paid within the due date but there was an issue at our end. So payment was not reflected and accounted within due date. Payment was accounted and reflected after 10 days of due date. I am unable to change payment term as system is giving below error:

ORA-20001: You can't update the payment schedule because the transaction has an activity against it.

Is there any solution other than posting credit memo? Please advise.
