I have put 999 days in configuration and system is doing any credit check further. But it applies to critical fields like payment terms & incoterms also. So if some one changes payment terms, incoterms system should trigger credit check and block the order..
It certainly tells us that we might be checking the wrong OVA8 combination here(credit control area,Risk category,Credit group)-Pl confirm. Also your screen shot of OVA8 does not confirms activation of critical fields.
I think normally condition group at item level will never changes the net value
(Until doing a manual update of pricing or condition group as used in any calculation formulae--Is it applicable in your case?? )
Here the question comes is- once an order released-when the user is changing the condition group(On the same day/next days)
If it is on the same day-normally it will not go again-until net value change..
if on Next days-definitely your configs will take for block again(released documents are still unchecked section is blank)
"""""Business Requirement: Adding the code should not cause the credit check to trigger but changing other fields such as: Payment terms, Incoterms, Due date, Price and Quantity, should trigger the Credit check""""""""
Your screen shot does not support this as critical fields are not active here.
Hope this helps.
