I'm trying to set an Inventory Items preferred Vendor Price. My code, see below, lets me commit and save the record with no issues or errors but does not change the value.

Weird. You’ve got to be on the right track. Your code works for me. I copied/pasted into the debugger, added

load()

,

selectNewLine()

, and

save()

and it worked for me. Here’s mine in the debugger:

require(['N/record']);
var record = require('N/record');

var itemRecord = record.load({ type: 'inventoryitem', id: 154, isDynamic: true });

itemRecord.selectNewLine({ sublistId: 'itemvendor' });

// Vendor
itemRecord.setCurrentSublistValue({
    sublistId: "itemvendor",
    fieldId: "vendor",
    value: 46,
    // ignoreFieldChange: true,
});
// Subsidiary
itemRecord.setCurrentSublistValue({
    sublistId: "itemvendor",
    fieldId: "subsidiary",
    value: 1,
    // ignoreFieldChange: true,
});
// Preferred
itemRecord.setCurrentSublistValue({
    sublistId: "itemvendor",
    fieldId: "preferredvendor",
    value: true,
    // ignoreFieldChange: true,
});
// Currency Name?
itemRecord.setCurrentSublistValue({
    sublistId: "itemvendor",
    fieldId: "vendorcurrencyname",
    value: "USA",
    // ignoreFieldChange: true,
});
// Purchase Price
itemRecord.setCurrentSublistValue({
    sublistId: "itemvendor",
    fieldId: "purchaseprice",
    value: 100,
    // ignoreFieldChange: true,
});
itemRecord.commitLine({
    sublistId: "itemvendor",
});

itemRecord.save();

are the purchase prices a subrecord?

possibly NetSuite OneWorld and in a subsidiary that uses a different currency.

yeah there are multiple settings that can cahnge the behavior of that vendor sublist

I think I should be using

itemvendorprice

instead of

purchaseprice
