Hi Suho, The scenario is, we should be able to trigger an alert when multiple shipping's are being caused by applying a single credit card. In our case this should occur when third distinct address pop's up in an event. So in my previous example, if we consider the 4th transaction which is,
*Colombo --> Kandy --> Colombo --> Kandy(4th)* This 4th transaction is not fraudulent since the credit card has been used only for shipments for two distinct addresses (Kandy & Colombo). But when the 5th transaction occurs from the same card, *Colombo --> Kandy --> Colombo --> Kandy --> Matara(5th)* The 5th transaction should be fraudulent, as it is the 3rd distinct address (Matara, kandy & Colombo) that is being shipped by using the same credit card. Thereafter, any transactions executed by the same credit card should also be fraudulent, as three distinct destinations are already available. So that is the requirement and I will use your examples and let you know. Thank you for the input suho.
