My client runned the dunning program via F150 for all the company's customers.
It is the first time the dunning program is runned. Dunning levels were updated manually via LSMW (changes have been made last month - February 2017). Globally F150 runned well but we noticed that some customers have dunning level 1 even if they are supposed to have higher levels according to both their previous dunning level and their late payment days.
I noticed that the dunning procedure has been changed for these customers (in July 2016). Unfortunately, I can't find a way to explain why F150 doesnt calculate the right dunning level for those cutomers and I dont know how to fix the problem.
Any help would be much appreciated.
Thanks in advance.
