can I make a column field required via a client script? if yes, please give me an example

AI generated answer (using internal Slack threads):

Yes, you can make a column field required via a client script in NetSuite. You can use the

isMandatory

property when creating the sublist field (column). However, it's important to note that this will make the entire column mandatory, not just specific lines. Here is an example of how you can enforce a field to be required at the line level when another field is filled at the line level. This example uses the

validateLine

entry point of a client script:

javascript
/**
 *@NApiVersion 2.0
 *@NScriptType ClientScript
 */
define(['N/currentRecord'], function (currentRecord) {
    function validateLine(context) {
        var currentRecord = context.currentRecord;
        var sublistName = context.sublistId;

        if (sublistName === 'your_sublist') {
            var field1 = currentRecord.getCurrentSublistValue({
                sublistId: 'your_sublist',
                fieldId: 'custcol_projectfield1'
            });

            var field2 = currentRecord.getCurrentSublistValue({
                sublistId: 'your_sublist',
                fieldId: 'custcol_projectfieldtask1'
            });

            if (field1 && !field2) {
                alert('Please fill out Field 2');
                return false;
            }
        }
        return true;
    }

    return {
        validateLine: validateLine
    };
});

In this script, when a line is added, it checks if

custcol_projectfield1

is filled and

custcol_projectfieldtask1

is not. If so, it shows an alert and prevents the line from being added until

custcol_projectfieldtask1

is filled. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
