The mapping algorithms provided with the base product record the mapped quantities in the calculation/audit read details collection on the bill segment. When regenerating a bill segment, it is possible that circumstance requires you to override the details in this collection rather than allowing the system to map the interval quantities again.

Refer to How To Override Service Quantities On A Specific Bill Segment for more information.

The pricing functionality in the algorithms provided by the base product detect when mapped quantities have been overridden and apply the TOU prices to the overridden quantities.
