This article explains how the Charge Segment metrics are mapped to the Charge Subtotal columns within the charge table in a renewal ramp Quote when the term is increased and multiple updates are made.

The following image shows a ramped renewal quote with term increase and multiple updates:

The ramp Quote originally had a renewal term of 12 months, but in the Renewal quote, the renewal term is updated to 24 months, resulting in a new Ramp Interval 2. In addition, multiple updates have been applied to the Recurring Per Unit charge.

• The first segment in Interval 1 runs from Jan 1, 2028, to Jan 30, 2028, with quantity 1. The recurring charges have a subtotal of 1 quantity * $10 price * 1 month = $10, and the delta is also $10.
• The second segment in Interval 1 runs from Feb 1, 2028, to Feb 28, 2028, and the quantity is updated to 2. The segment's subtotal and delta are calculated as 2 quantity * $10 * 1 month = $20.
• The third segment in Interval 1 runs from Mar 1, 2028, to Dec 31, 2028, and the quantity is updated to 3. This segment's subtotal and delta are calculated as 3 quantity * $10 * 10 months = $300.

The following is the Period Metrics JSON response, which may be compared with the Quote Studio UI to see how it maps.
