Netsuite Invoice Line Item not adding

My Restlet should either add or update an invoice with the line items. The add bit works - invoice + line items, but the update doesn't appear to add a new line item. Code looks like this:

update_record = nlapiLoadRecord('invoice', invoice_id)
var itemcount = update_record.getLineItemCount('item');
for (var i = 0; itemcount != null && i < itemcount; i++) {

	if (jsonobject.item[i].item) {
	
		update_record.setLineItemValue('item', 'item', i + 1, jsonobject.item[i].item)
		
	}
}
var id = nlapiSubmitRecord(update_record, true);
nlapiLogExecution('DEBUG', 'id = ', id)
return id;

Solution

  • Instead of setLineItemValue, try using the series of selectLineItem, setCurrentLineItemValue, and commitLineItem methods. setLineItemValue is not supported in all scenarios or on all fields.

    See the NS Help article titled nlobjRecord for details on all of these methods.
