The large batch was a combo of VISA transactions, some invoices had tax included, some not. Those that did not have the tax account code were posted properly. All invoices that included the tax account code were rejected. This account code is our main code used in all of our typical transactions and is set to active in the GL.
I attempted a very simple two line invoice with the tax code included and it was rejected with the same message as above.
Any other options?
