record.transform

method in SuiteScript to transform an invoice into a customer payment, which can then be used to apply the credit memo. Here is a simplified example:

javascript
var invoiceId = '123'; // replace with your invoice internal id
var creditMemoId = '456'; // replace with your credit memo internal id

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

var lineCount = customerPayment.getLineCount({ sublistId: 'apply' });
for (var i = 0; i < lineCount; i++) {
    customerPayment.selectLine({ sublistId: 'apply', line: i });
    var applyInvoiceId = customerPayment.getCurrentSublistValue({ sublistId: 'apply', fieldId: 'internalid' });
    if (applyInvoiceId == invoiceId) {
        customerPayment.setCurrentSublistValue({ sublistId: 'apply', fieldId: 'apply', value: true });
        break;
    }
}

lineCount = customerPayment.getLineCount({ sublistId: 'credits' });
for (var i = 0; i < lineCount; i++) {
    customerPayment.selectLine({ sublistId: 'credits', line: i });
    var applyCreditMemoId = customerPayment.getCurrentSublistValue({ sublistId: 'credits', fieldId: 'internalid' });
    if (applyCreditMemoId == creditMemoId) {
        customerPayment.setCurrentSublistValue({ sublistId: 'credits', fieldId: 'apply', value: true });
        break;
    }
}

customerPayment.save();

This script first transforms the invoice into a customer payment. It then loops through the 'apply' sublist to find the invoice and sets the 'apply' field to true. It does the same for the 'credits' sublist to apply the credit memo. Finally, it saves the customer payment record, which applies the credit memo to the invoice. Please replace

'123'

and

'456'

with your actual invoice and credit memo internal ids.
