Skip Credit Check based on an Item

Hi Team,

We are trying to skip credit check in OM using groovy extension, Requirement is to skip the credit check if we find 191919 item in the order. Our code is working fine for a new order but when we try to create an order revision and add item: 191919, it still goes to Credit review. We tried printing the PreCreditCheckFlag and it is showing as 'Y', We are not sure why order is still going for a credit check. Could you please advice on the potential solution.
