Scott, I am not sure OE has anything that can help you as it sounds to me like an application issue. Unless of course I am misunderstanding your questions. It sounds like what you are saying is you have a Point of Sale application written in OpenEdge and that the application logic caused a credit card to be charged twice. I would hope that the application logic would be logging pertinent information in their logs that would help you diagnose it. Being in the POS business for 35 years I can tell you I have seen this issue on numerous occasions. Typically, the processor will have duplicate transaction checking that prevents this as the same CC number, for the same amount with the same transaction number from the same merchant MUST be a duplicate. In our POS module we use a 3rd party for integrated payments and we will log the xml request we send and the xml response we receive. We could definitely tell if we sent the request more than once. I am not sure that helps or not.
