Creating sales order having subscription item for physical product requiring recurring fulfilments

Summary:

Customer wants to create sales orders containing subscriptions of physical (shippable) products which are to be shipped every month (periodicals / magazines/ journals etc). The requirement is similar to the steps described in the section "Add Subscription to Sales Order" of the Order Management User Guide 23D

When we tried to create such a sales order, we could add the item to the order and price it. However, only one fulfillment line got created for the subscription line (for the first month only), instead of multiple recurring fulfillment lines - one for each month throughout the duration of subscription. We used the DOO_ProductFulfillmentWithIntegratedSubscription for these types of orders.
