This article handles another common issue, seen when handling documents containing Item Tracking lines in NAV 2009.
In this instance, the problem affects Sales and Purchase Invoices and occurs when splitting the relevant shipment or receipt lines and then posting the invoice.
Both solutions should be applied where appropriate, as the issues affect similar aspects within Sales and Purchasing.
