Has anyone encountered issues with Due Dates intermittently not calculating on AR Invoices in NAV 2018? I am looking at two invoices for the same customer, one is correct the other is missing the Due Date - both have the same Net30 Terms assigned on the Invoices. I confirmed that the Terms code is setup correctly. I am trying to figure out how best to trace this back to see how it either may have been cleared or simply did not calculate.
