Billing Rounding Issue In Billing Time Taxation With AR Rounded To 2 (Doc ID 2793527.1)

Last updated on JULY 23, 2021

Applies to:

Oracle Communications Billing and Revenue Management - Version and later
Information in this document applies to any platform.


In the current deployment of Billing and Revenue Manager (BRM), when A/R rounding is 2 dp (digits precision) whilst charges are at 3dp, /item rounding is done on a per-item basis, and does not provide any mechanism to apportion the rounding error over other items or generate an event to track it… it just rounds the item.

The following example illustrates this scenario:

(before billing)        (after billing)  
  Unrounded          Rounded Due          Delta_due
    4.545              4.55                    0.005
    10                   10                      0
    4.545              4.55                    0.005
    10                  10                       0
    ---------         -----------          -------------
    29.09              29.1                   0.01

Before billing:
Bill total = 29.09 + 10% tax => 29.09 + 2.90 (2.909) => 31.99

After billing:
Bill total = 29.1 + 10% tax => 29.1 + 2.91 => 32.01

As tax is calculated on the unrounded total (before bill finalization), it is calculated on 29.09 whilst the bill total after rounding becomes 29.1 … there is a difference of 2 cents.
