Example 3

For another example, suppose that you have subscribed a customer to 10 units of your product for 2 months, with a monthly billing period and a list price of $5.00 per unit per month. The charge starts on the 1st and the billing period starts on the 16th.

The corresponding Rate Plan Charge (actually the charge segment RPC-1) will have a TCB of $97.4 = $50(1 full billing period) + $24.2 (for the starting partial period, 50*15/31, 15=[2021-01-01, 2021-01-15], 31=[2020-12-16, 2021-01-15]) + $23.2 (for the ending partial period, 50*13/28, 13=[2021-02-16, 2021-02-28], 28=[2021-02-16, 2021-03-15]) from 2021-01-01 to 2021-03-01.

After one and half months, you place an order and increase the quantity to 13 units from 2021-02-16, so that the TCB of the Rate Plan Charge becomes $104.4 = $50(1 full billing period) + $24.2 (for the starting partial period, 50*15/31) + $30.2 (for the ending partial period, 65*13/28).

The above changes are interpreted as an OrderDeltaTcb of -$23.2 for RPC-1 between 02-16 to 03-01, due to the fact that the duration of RPC-1 has shrunk; and an OrderDeltaTcb of $30.2 for RPC-2 between 02-16 to 03-01, because Zuora creates a new RatePlanCharge object for the new price from 02-16 to 03-01, as shown below.
