I am newbie to NetSuite and wanted to show vendor names in specific format while displaying. Currently each vendor has auto-generated id with some prefix e.g.

ABC0001
ABC0002
ABC0003

These vendors are then shown as a sublist in other pages as following:

ABC0001 Mr. Vendor A
ABC0002 Mr. Vendor B
ABC0003 Mr. Vendor C

I want to show vendor name as Name only, without the id in sublists like below:

Mr. Vendor A
Mr. Vendor B
Mr. Vendor C

How is that possible? Currently I tried to use following SuiteScript, but its not working:

define(["N/record"], function (record) {
  /**
   *@NApiVersion 2.0
   *@NScriptType ClientScript
   */

  function pageInit(context) {
    var itemRecord = record.load({
      type: record.Type.INVENTORY_ITEM,
      id: context.currentRecord.id,
      isDynamic: false,
    });

    var lines = itemRecord.getLineCount({ sublistId: "itemvendor" });

    for (var i = 0; i < lines; i++) {
      var vendorName = itemRecord.getSublistText({
        sublistId: "itemvendor",
        fieldId: "vendor",
        line: i,
      });

      var parts = vendorName.split(" ");
      parts.shift();
      vendorName = parts.join(" ");

      itemRecord.setSublistText({
        sublistId: "itemvendor",
        fieldId: "vendor",
        line: i,
        text: vendorName
      });
    }

    itemRecord.save();
  }

  return {
    pageInit: pageInit,
  };
});

Any idea what am I doing wrong here? Or is this even the right way to do it? Any help will be greatly appreciated.

Thanks
