please write a client script (deployed on transaction, e.g. vendor bill) that will make a line field (column field) disabled when a user is on the respective line

AI generated answer (using internal Slack threads):

Based on the conversations, it seems like you want to disable a line field on a transaction form (like a vendor bill) when a user is on the respective line. You can achieve this by using a client script in NetSuite SuiteScript. Here's a sample script that you can use as a starting point:

javascript
/**
 * @NApiVersion 2.x
 * @NScriptType ClientScript
 * @NModuleScope SameAccount
 */
define(['N/currentRecord'], function(currentRecord) {
    function lineInit(context) {
        var currentRecordObj = currentRecord.get();
        var sublistName = context.sublistId;
        var line = currentRecordObj.getCurrentSublistIndex({ sublistId: sublistName });

        var theField = currentRecordObj.getSublistField({
            sublistId: sublistName,
            fieldId: 'your_field_id', // replace with your field id
            line: line
        });

        theField.isDisabled = true;
    }

    return {
        lineInit: lineInit
    };
});

This script uses the

lineInit

entry point, which is triggered when a user navigates to a sublist line in edit mode. It gets the current line index and disables the field on that line. Please replace

'your_field_id'

with the actual ID of the field you want to disable. Remember to deploy this script on the transaction record type where you want this functionality. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
