We are using OE 8.1C second month. Since ubgrade we experiencing the following issue:

After retrieving OE and AR transactions we find out that AR clearing balance is not equal to zero. The additional analysis shows that variance was the invoice discount(s), invoice amount not posted properly to clearing account. However, OE does proper calculation on "total" tab of the invoice (Net Amount - 31,638.45). Please see details of retrieved transactions below:

Accounts Receivable - Clearing Details

Description Trx Date Ledger Type Reference Amount
Cust. Name 08/02/11 AR IN 135004 (31,638.45)
Cust.inv 135004 08/02/11 OE IN DAY 2825 32,253.37

Is this known problem? Is there a fix? Is this issue related to our installation/configuration only?
Please advise.

Thank you
Victor Belan
