How to change International Ship to Address for ShipTo Partner in Sales Order

[100564E11]

Hello 

I have a requirement to change the international Ship To address in Sales Order whenever its National Address is changed.

Currently via standard mechanism , only the POSTAL code and COUNTRY is being copied.

Can anyone suggest a BADI or a USER EXIT to do the required change? 

In short , my requirement is to copy any changes from Screen 1(national address) to Screen 2(International Address)

Currently as per standard logic only Country and Postal Code are being copied.

Steps to reach here :

Open any Sales Order

-> Display Header Details

->Partner Tab

-> Double click on the ShipTo Partner number , The popup that opens up is National Address

on the top of the pop up screen you might find a button 'International Versions' , this should have your international address. 

Regards,
