Hi Amlan,
Thanks for the feedback.
Important point I forgot to mention is that the dunning no longer stops at the final level. We keep sending the customer reminders for the full amount as long as the amount level is not reached. This means I need to dun including the items that are currently at level 3.
I guess I'll just have to see if it works and if not I can probably do something in event 304 to fix this.
