When a Sales Representative decreases the quantity of an asset:

• If the billing schedule is "Pending Billing", Billing supersedes the old billing schedule and creates a new billing schedule for the remaining quantity.
• If the billing schedule is "Invoiced", Billing creates a negative billing schedule to refund the amount and creates a new billing schedule for the remaining quantity.

For more information on asset quantity decrement, see Managing Asset Decrement.

Use Case 1: Changing Billing Schedules in "Pending Billing" Status for a Decremented Asset

This use case describes how Billing supersedes the old billing schedule and creates a new billing schedule with the decremented quantity. Before the sales representative changes the asset quality, the billing schedule details are as follows:

Schedule	Period Start Date	Period End Date	Quantity	Status	Fee Amount	Type	Is Superseded	Ready for Invoice Date
BS1	1/1/2022	12/31/2022	4	Pending Billing	USD 400.00	Contracted		1/1/2023

After the Sales representative decreases the quantity from 4 to 3, the Cart page has the following details:

• Quantity = Negative quantity provided by you on the Change Quantity page
• Line Status = Decremented and Merged
• Net Price = Amount for the quantity decremented

On order activation, the decrement quantity updates into the existing asset. The asset line item has the following details:

• Asset Status = Activated
• Net Price = Amount for the remaining quantity after decrement
• Quantity = Remaining quantity after decrement
• Asset TCV = Reflects the right value

Billing Schedules are created as follows:

Schedule	Period Start Date	Period End Date	Quantity	Status	Fee Amount	Type	Is Superseded	Ready for Invoice Date
BS1	1/1/2022	12/31/2022	4	Superseded	USD 400.00	Contracted	Yes	1/1/2023
BS2	1/1/2022	12/31/2022	3	Pending Billing	USD 300.00	Contracted		1/1/2023

Use Case 2: Changing Billing Schedules in "Invoiced" Status for a Decremented Asset

This use case describes how Billing creates a negative billing schedule to refund the amount for the decremented quantity. Before the sales representative changes the asset quality, the billing schedule details are as follows:

Schedule	Period Start Date	Period End Date	Quantity	Status	Fee Amount	Type	Is Superseded
BS1	1/1/2022	12/31/2022	4	Invoiced	USD 400.00	Contracted

After the Sales representative decreases the quantity from 4 to 3, the Cart page has the following details:

• Quantity = Negative quantity provided by you on the Change Quantity page
• Line Status = Decremented and Merged
• Net Price = Amount for the quantity decremented

On order activation, the decrement quantity updates into the existing asset. The asset line item has the following details:

• Asset Status = Activated
• Net Price = Amount for the remaining quantity after decrement
• Quantity = Remaining quantity after decrement
• Asset TCV = Reflects the right value

Billing Schedules are created as follows:

Schedule	Period Start Date	Period End Date	Quantity	Status	Fee Amount	Type	Is Superseded
BS1	1/1/2022	12/31/2022	4	Invoiced	USD 400.00	Contracted	Yes
BS2	1/1/2022	12/31/2022	3	Pending Billing	USD –100.00	Contracted
