Prevent Finishing Invoices When Serials are not Allocated to Warranty Lines
By default, sales staff can finish invoices for extended warranty products without adding a serial and model to the warranty line. To enforce the requirement for serials on invoices, follow these instructions:
Enabling the "Prevent Finishing If Serials Are Not Allocated" Option
- 
Navigate to Tools > System Maintenance.
 - 
Click the Variables tab.
 - 
Select Invoicing, and then click Open.
 - 
On the General tab, enable Prevent Finishing If Serials are not Allocated on Warranty Lines.

 - 
Restart EPASS for the change to take effect.
 
- 
A customer wants to purchase an extended warranty a few weeks after their appliance purchase. The salesperson does not add the model and serial to the Warranty tab.

 - 
An admin clerk attempts to finish the invoice. A message box appears, alerting them that "Models have not been allocated!"
 - 
The admin clerk cannot finish the invoice until the model and serial are added to the warranty line.
