How can I override the amount calculated by NetSuite on a invoice item line? I don't want to modify the rate, but I need to update the amount field. Even though I receive a warning message saying the amount isn't calculated correctly, NetSuite still overrides it upon saving.

AI generated answer (using internal Slack threads):

To override the amount calculated by NetSuite on an invoice item line, you can use a User Event (UE) script or a Client script. However, it's important to note that NetSuite's standard behavior is to calculate the amount based on the rate and quantity. If you manually override the amount, you may receive a warning message, but the system should still save your changes. Here's a general approach you can take: 1. Create a User Event (UE) script or a Client script that triggers on the record load or field change event. 2. In your script, access the line item sublist using the

record.getSublistSubrecord()

method. 3. Use the

record.setValue()

method to set the amount field to your desired value. Please note that this approach may not work in all cases, as some fields on the sublist may not be editable depending on the record type and context. Also, be aware that setting sublist lines in a beforeLoad event may not work as expected, as sourcing doesn't happen in this context. Here's a sample code snippet for a User Event script:

javascript
function beforeSubmit(context) {
    var record = context.newRecord;
    var lineCount = record.getLineCount({sublistId: 'item'});
    for (var i = 0; i < lineCount; i++) {
        var quantity = record.getSublistValue({sublistId: 'item', fieldId: 'quantity', line: i});
        var rate = record.getSublistValue({sublistId: 'item', fieldId: 'rate', line: i});
        // Calculate your custom amount here
        var customAmount = calculateCustomAmount(quantity, rate);
        record.setSublistValue({sublistId: 'item', fieldId: 'amount', line: i, value: customAmount});
    }
}
