User Story

As a Communication Service Provider, I need the possibility to assign several Sales discounts whose periods overlap on the same commitment — where any shared day, including a day on which one discount's period ends and another's begins, applies all overlapping discounts together — so that I can combine stacked promotional offers (for example a general onboarding discount and a shorter seasonal top-up) over the same period and bind customers to long-term commitments without having to split or manually merge the offers.

Current Solution

Currently, it's not possible to configure overlapping sales discounts because of the validation on the back-end side implemented in BA-44107 for MR125-3 and higher.

Use Cases

Use case #1: Assigning Sales discounts with overlapping periods

Roles: Administrator, CRM System, call center operator.

Preconditions: Customers are offered with additional discounts during Commitment signing. Monthly billing periods are used in scenarios.

Use scenario #1.7 Assigning Sales discounts with overlapping periods

Continued after: the packages and preconditions of Use case #1. Monthly billing periods are used. An overlap is any case where the [start date; end date] period of one Sales discount overlaps the period of another, including the case when one period ends exactly on the day the other begins (e.g. a discount for 01.08 - 10.08 and a discount for 10.08 - 20.08 overlap on 10.08). On every overlapping day all overlapping Sales discounts are applied together (summed).

• Customer John Smith signs a commitment for 24 months for period 02.06.2019 - 02.06.2021 for 'TV: 78 basic channels' package.
• On signing the commitment John Smith is offered two Sales discounts for the service fee whose periods overlap:
• Discount A: 6.00 EUR/month for period 02.06.2019 - 01.09.2019 (3 months).
• Discount B: 4.00 EUR/month for period 02.08.2019 - 01.11.2019 (3 months).
• The periods of Discount A and Discount B overlap for the window 02.08.2019 - 01.09.2019. On every day of this window both discounts are applied to the service fee and their amounts are summed.
• Starting from 02.06.2019 John Smith starts using service and fees start to be applied from this date to him.
• On 01.07.2019 monthly charges are calculated and applied to the balance of John Smith.
• On 01.07.2019 invoice for June is generated. Only Discount A is active in June (Discount B starts on 02.08.2019):

• John Smith pays invoice and continues using service.
• On 01.08.2019 invoice for July is generated. Only Discount A is active for the whole month (service fee 13.50 EUR - 6.00 EUR = 7.50 EUR, rent fee 2 EUR). John pays it.
• 02.08.2019 is the first day of Discount B. From 02.08.2019 to 01.09.2019 both Discount A and Discount B are applied to the service fee.
• On 01.09.2019 monthly charges are calculated and applied to the balance of John Smith.
• On 01.09.2019 invoice for August is generated. In August Discount A is applied for all 31 days (01.08 - 31.08); Discount B is applied for 30 days (02.08 - 31.08). Both discounts are applied together on the overlapping days:

• John Smith pays invoice and continues using service.
• 01.09.2019 is the last day of Discount A. This day also belongs to the period of Discount B (which runs until 01.11.2019), so 01.09.2019 is a shared boundary day on which both discounts are applied - this is an overlap according to the customer's definition. Starting from 02.09.2019 only Discount B remains active for the service fee.
• On 01.10.2019 invoice for September is generated. Discount A is applied only for 1 day (01.09.2019); Discount B is applied for all 30 days of September:

• John Smith pays invoice and continues using service. Starting from 02.11.2019 no Sales discount is applied for the service fee.
