Hi Sang, as you already said: Koha recalculates the fines every day. If you change the configuration, it will also apply for existing fines on the next day. I agree that this can be a problem, but I don't know of a way to avoid it. Katrin On 28.02.2018 13:46, ksang wrote:

Hello,

We do want to setup new fine rates for overdue without affecting the existing fines for patrons who have not paid.

However when we effect the new fines, koha calculates all fines using the current rates. What are we doing wrong?

Regards,

sang
