Negative Quantity Usage

Overview

You can upload usage records of negative quantity to adjust the previously uploaded usage records, in the following manner:

• Use the CRUD: Create a usage record operation to upload a usage record of a negative quantity.
• You can upload a usage record of a negative quantity to the same billing period of a previously uploaded usage record while this billing period is open.
• You can also upload a late usage record of a negative quantity when a billing period is closed. In this case, a credit memo or invoice item adjustment is generated in the next billing period for the late usage record of a negative quantity. 
• When you use unit-based prepaid with drawdown, if you upload a usage record of a negative quantity, a prepayment adjustment is generated for the prepayment charge. This is the case even if you upload a late usage record of a negative quantity.
• When you use currency-based prepaid with drawdown or currency-based minimal commitment:
  • If you upload a usage record of a negative quantity to an open billing period, a Prepayment Adjustment transaction is generated for the prepayment charge to increase the prepayment balance.
  • If you upload a late usage record of a negative quantity, a credit memo or invoice item adjustment is generated in the next billing period for the late usage record of a negative quantity.
