Thank you for your advise and opinion.
I see where you coming from especially as an SAP developer dealing with business user like me who trying to be a "smart-***" 
by using the word "2nd opinion" "holding our SAP team accountable"
I assure you that is not my attention. I am just trying to do with limited IT resources we have, tickets are backlogged and I have to gain understanding faster than the projected time they have allocated for our dept. When it comes to our time, I can speak some of the "language" and perhaps they can understand it right away. That is all.
Also although I have a curious mind, in no way I have the knack to go/or develop skills in this direction, this is just an attempt to help the team here. I do read and compare, and make judgment as to which advise/opinion from a "random person" (you are not random by your historical posts and/or badges btw - you're an expert) to take in.
Back to OVA8, apparently I do have view access. "no modification"
And I can see each Risk Category has CG 01 and CG 02 with some details in it. I can see now what triggers past due for each risk category.
Your first comment was % was not a good idea, but I see theres Max.open.item%. With credit Limit 1M, would putting 1% ignore all past due items up to $10,000?
Where in OVA8 can a setup for specific amount be set?
