It is mandatory to define a zip code for the customer unless when the address presentation is defined without ZIP code and the address is related to that address presentation, it should be possible to send invoices without error. Therefore require to set up the address presentation accordingly both in display layout and edit layout (in this case with no ZIP Code).

Please check the bug 153874 which was introduced to handle situations where countries such as Angola doesn't have ZIP code thus ZIP codes are not registered for all customers.

Hi Janith

As far as I know, zip code is not mandatory when setting basic data for e-invoice functionality for customer invoices.

As Shehan said,  user can can configure the address layout from Address Presentation window in IFS application for specific countries.

Hi,

Before introduction of bug 153874, there were some support cases reported by customers because their invoices were stuck in customer invoices with errors window with below send errors.
• Invoice Address Zip Code must have a value
• Delivery Address Zip Code must have a value

After introducing the above bug, customer got the opportunity to use E-invoice functionality for customers do not have Zip codes in their countries. 

Kind Regards,

Kalpa.
