I want to apply a credit memo to an invoice via SuiteScript do I need to create a customer payment for that?

AI generated answer (using internal Slack threads):

To apply a credit memo to an invoice via SuiteScript, you do not necessarily need to create a customer payment. However, creating a customer payment is the standard approach to apply different transactions to the invoice, including credit memos, unapplied payments, and journal entries. You can use the

record.transform

method to mimic the effect of the 'Accept Payment' button in the UI. This method transforms the invoice into a customer payment. Then, you can use the

Record.setSublistValue

method to mark the same checkboxes you would in the UI, which would apply the credit memo to the invoice. Here is a sample code snippet:

javascript
var payment = record.transform({
    fromType: record.Type.INVOICE,
    fromId: invoiceId,
    toType: record.Type.CUSTOMER_PAYMENT,
    isDynamic: true,
});

var lineCount = payment.getLineCount({ sublistId: 'apply' });
for (var i = 0; i < lineCount; i++) {
    var apply = payment.getSublistValue({ sublistId: 'apply', fieldId: 'apply', line: i });
    if (apply) {
        payment.setSublistValue({ sublistId: 'apply', fieldId: 'apply', line: i, value: true });
    }
}

payment.save();
