I am using eBusiness Web Services to integrate our shopping cart with Sage 100 ERP. In the process of adding a sales order, one must preauthorize a card with the PreAuthorizeCreditCard method of the web services. In the results, there is a field called ApprovalIndicator. Unfortunately, this method is not fully documented, and I do not know all the possible values that it returns. Through testing, I have found that it returns "A" for approved, but I do not know what it may return in case the card is declined.

Does anyone here know all the possible ApprovalIndicator values that this method returns? Any help would be greatly appreciated. Please let me know if I need to provide any more information.

Thanks in advance.
