FWIW, we have had two Sale Order Invoicing events in the last couple weeks, one from a client (MAS 200 4.4) and one from our in house system (MAS 200 4.5)
The client had a Sales Order Invoice with two backordered items and 4 shipped items. The invoice added one of the backordered items to the Invoice Total. The line on the invoice showed one ordered, one backordered, the correct price and an extension of zero; however, the amount for this item was added to the invoice total. The item in question was still available to ship.
On our in house system, a Sales Order Invoice consisting of 11 miscellaneous items (All related to Managed Services, some taxable and some not) dropped two items off the invoice total. In this case the quantities were ordered and shipped and the price and extension were there. The extensions did not make it to the invoice total.
In both cases, the AR Open Invoice, AR Invoice History Header, the related Tax Summary files and the AR Transaction Payment History File were affected. The AR Invoice History Lines files were fine. Also, the DTR was out of balance in both cases with the error being in the AR account.
There were no displayed errors or activity log entries.
I would be interested to know if anyone else has seen this or similar issues.
