This is just an FYI to others who use scripts.

I have two scripts that started having issues after 2017.1 upgrade. In both cases, certain fields are set on a new record object and submitted successfully, but the record in NS shows the fields as null or default value. In both cases, I am able to work around by resubmitting the fields a second time. I am not willing to submit a case to NetSuite because I know it's a time drain and they will make me prove that it's their issue, plus there's a workaround so it's unlikely to get fixed. But I at least feel obligated to tell other users to watch for this kind of problem. Again, these scripts were working successfully in 2016 and previous releases, and only now show this behavior.

Example 1, using nlapiSubmitField()

Code:
…
var child_record = nlapiCopyRecord('salesorder', parent_id);
child_record.setFieldValue('customform', child_form);
…
var id = nlapiSubmitRecord(child_record, true);
nlapiSubmitField('salesorder', id, 'customform', child_form, false); // custom form not working on original submit, try updating 22-May-2017

Example 2, have to reload the record and cycle through all items to update

Code:
…
while (qty_remaining > 0) {
…
receive_record.setLineItemValue('item', 'binnumbers', earliest_line, bin);
…
}

var submit_receive = nlapiSubmitRecord(receive_record, true); // USAGE = 20

// binnumbers not working on original record submit, have to reload the record and update the field on each line — added 20-May-2017
var record_resubmit = nlapiLoadRecord('itemreceipt',submit_receive);
var lines_resubmit = record_resubmit.getLineItemCount('item');
for (var x = 1; lines_resubmit && x<=lines_resubmit; x++){
record_resubmit.setLineItemValue('item', 'binnumbers', x, bin);
}
var try_again = nlapiSubmitRecord(record_resubmit, true);
