How to import supplier sites where the address name should not be site name.

 HI All,
Business requirement is have the supplier site name as A (vendor_site_code) but the address name as B (party_site_name). We tried populating these fields in the apps.ap_supplier_sites_int table but import fails if we specify anything in party_site_name column. If we leave party_site_name as blank then it creates the vendor by the name A but address name also comes as A !

Regards,
Arvind
