A change has been made to how the Default Stock Area configuration is used. When completing an Invoice using any of the invoicing system options (Standard Invoice, Standard Credit Invoice, etc) the system will no longer look at the Default Stock Area Configuration in Invoice Configuration. It will look at the Ports (computers) Port Parameters and get the Default Stock Location from there.
When you open an Invoicing screen for the first time on a new port (computer) the Port Parameters window will display asking you to set the Default Stock area for this port. For further information about this change please see the update Port Parameters – Setting Default Stock Area’s within ACR
