Change variation product

If an order has variation products, an Edit icon is displayed corresponding to the attributes of such products. For example, a T-shirt could have size and color as attributes that can be changed based on customer’s needs. When the store associate clicks the Edit icon, the Product Details screen is displayed where the appropriate attributes can be selected. Once the order is updated with the variation product, the Edit Order screen is displayed with the refreshed data. The modifyFulfillmentOptions API is called to cancel the old variation product and add a new variant product. When the store associate clicks Save in the Edit Order screen, the changeOrder API is called to commit the changes to the database.
