The recommended way to identify the prospects who purchased a certain product within the last year and export them to a .csv file is to create a segmentation rule based on the Product Name field. A segmentation rule is a one-time rule that matches prospects based on certain criteria and performs certain actions. You can create a segmentation rule that matches prospects who have the specific product name in the Product Name field and the action to export them to a .csv file. This way, you can get a one-time export of all the prospects who have the product name before it changes. An automation rule, a completion action, or a dynamic list are not suitable for this goal, as they are either recurring, real-time, or based on an activity, not a one-time export based on a field value. References [Segmentation Rules Overview]
