UBR/UER Balances after invoice cancellation & revenue write-off

 Dear All,

We are encountered with an  issue where after invoice cancellation & revenue write-off , the UBR/UER is not nullified ( Event Amount Revenue & Invoice = 292500) . Pls have a look at the below mentioned scenario:

step1: Invoice generated ( Advance Billing)  before revenue hence it hit the UER creating +ve entry in UER

step2: Revenue Generated (After Invoicing) hence it also hit UER  creating -ve entry in UER.

As a result of step 1 & 2  UER gets nullified.

Due to some reason the invoice need to be cancelled & revenue to be write-off. so we followed the  below steps:

step 3: cancelled the original invoice and UER is hit creating -ve entery in UER.
