Merchandise Segmentation - Installment Billing
If your organization allows customers to purchase merchandise using an installment plan, you must create a SA type for this.
Note: 
No installments. If the customer must pay for the merchandise in one lump amount, you'd create an SA type similar to the Connection Charge Segmentation example.

The recurring charge control information is set up as defined.
