Hi, I'm new to AX development and would like to customize the CustCustomer AIF service. I would like it to check each Customer record and if it already exists in the CustTable then do not insert it and continue with the next Customer record. I think I can do this validation in the prepareForSave method in th AxdCustomer class. If I return false from this method, then the customer is not saved. The only problem is that the AifEntityKeyList returned from CustCustomerService.create still contains the IDs of all the Customers that were skipped. I need a list of only the customers that were inserted into the custTable. Any ideas?
