How to get cumulative price to work with Price breaks based on usage counters

Hi All,

we have a service contracts case where a usage counter needs to be billed not based on the price break defined for the actual counter reading but on the cumulative value of the price break.

For example,

We have a price break (by point) defined of number of cards processed per year where:

0-40000: 1.34

40001-60000: 1.30

60001-80000: 1.26

80000-9999999999: 1.22

The counter that are are using is a change counter which means that we only capture the readings for the billing period that require to be charged - so past month we have a counter value of 5000.

However, the total counter during this year is set to 75500 which with the additional 5000 would mean that the 5000 needs to be priced at 1.22 (final price = 6100) and instead the 5000 are priced at 1.34 (final price = 6700)
