Hi Gregg,
The reason might be that the Distribution calendar connected to the site has been expired, hence the system is unable to calculate the delivery date of the customer order. (Open Application Base Setup\Enterprise\Site\Site, query for the site and select the calendar that is used as “Distribution calendar” and check the end date). To solve the issue please edit the “End date” of the calendar to the needed value and generate the calendar. Then again try to approve the Invoice Preview and check.
Hope this helps.
Best Regards,
Yasanthi
