In OpenERP first create delivery address in delivery form and then we need to define a partner for the brand of the product and also dedicated_delivery_address stand for the case a new type of address. In stock form move all the delivery address to stock move form and return the partner delivery address.

Use this function given below

def return_address(self, cr, uid, ids, field_names, arg, context=None):

        result ={}
        address_obj = self.pool.get('res.partner.address')
        for supplier_info in self.browse(cr, uid, ids, context=context):
            result[supplier_info.id] = {}
            address_id = False
            return_partner = supplier_info.warranty_return_partner
            if return_partner:
                if return_partner == 'supplier':
                    partner_id = supplier_info.name.id
                elif return_partner == 'brand':
                    if not supplier_info.product_id.product_brand_id.partner_id:
                        raise osv.except_osv(_('Error !'), _('You need to define a partner for the brand of the product !'))
                    partner_id = supplier_info.product_id.product_brand_id.partner_id.id
                else:
                    partner_id = supplier_info.company_id.partner_id.id
                address_id = address_obj.search(cr, uid, [('partner_id', '=', partner_id), ('type', 'like', 'dedicated_delivery')], context=context)
                if not address_id:
                    address_id = address_obj.search(cr, uid, [('partner_id','=', partner_id), ('type','like','delivery')], context=context)
                    if not address_id:
                        address_id = address_obj.search(cr, uid, [('partner_id', '=', partner_id), ('type', 'like', 'default')], context=context)
                if not address_id:
                    raise osv.except_osv(_('Error !'), _('No address define for the %s!') % return_partner)
                result[supplier_info.id] = address_id[0]
        return result
