Hi Experts, I have a customer and order entity with one to many associations so that one customer will have multiple order details. Here I am adding customer and their order details via Excel Import, and did successfully. REQUIREMENT: 1) Here I am importing customer and their order details in a single excel sheet, I want to check whether the imported customer data is existed already or not, if it is existed I want to map those new order details to the existed customer. 2) If the customer is not existed I want to create a new customer object and I need to map those order details for the new customer. Answers are really Appreciated!
