Regional structure in Sales Orders

Hello,

I'm trying to use the regional structure functionality in SAP. It allows users to find a city when enterring a postal code and vice versa. My concern is that it seems applicable when we want to enter or change an address in Sales Orders because (and it's hardcoded) several fields (eg city field) are mandatory in the SO addresses.

Why add this functionality if it can't be used?

Note 582851 has apparently been replaced by note 1469064. Did you succeed to use regional structures in Sales Orders? Is there any way to succeed?

Best regards,

Catherine MICHEL
