I can set shipping address just fine on the sales order. But billing address is not setting. Any ideas why? Same fields, same function just different objects passed.

what does the code look like

const addAddress = (addrRec, addrObj) => {
    addrRec.setValue({fieldId: 'country', value: addrObj.country});
    addrRec.setValue({fieldId: 'addressee', value: addrObj.addressee});
    addrRec.setValue({fieldId: 'attention', value: addrObj.attention});
    addrRec.setValue({fieldId: 'addr1', value: addrObj.addr1});
    addrRec.setValue({fieldId: 'addr2', value: addrObj.addr2});
    addrRec.setValue({fieldId: 'city', value: addrObj.city});
    addrRec.setValue({fieldId: 'state', value: addrObj.state});
    addrRec.setValue({fieldId: 'zip', value: addrObj.zip});
};
if (orderData.billing_address) {
    log.audit('billing_address')
    let billAddr = orderData.billing_address;
    salesOrder.setValue({fieldId: 'billaddresslist', value: '-2'});
    let billingAddrRec = salesOrder.getSubrecord({fieldId: 'billingaddress'});
    addAddress(billingAddrRec, {
       addressee: billAddr.first_name + ' ' + billAddr.last_name,
       attention: billAddr.company,
       addr1: billAddr.address1,
       addr2: billAddr.address2 || '',
       city: billAddr.city,
       state: billAddr.province,
       zip: billAddr.zip,
       country: billAddr.country_code
    });
}

@battk

don't set the

billaddresslist

, netsuite will set it automatically in most cases
