I understand that one of the field's from the recurring framework need to be part of the product and by extension a rule needs that to create a recurring entity by getting the products that have recurring field in them.
I had added the recurring field in the line items types that are of the type add to cart, so that the customer can pick what kind of recurrence they want instead of adding it to the product. These type of fields do not get picked by the Get Recurring Product action in the rules and no recurring entity is created.
Any advice on how to make this work so customers can decide the period rather than the store providing different subscription options by creating that many products?
