i want to initialize a credit memo with specific invoices applied how can I do that in suitescript

AI generated answer (using internal Slack threads):

To initialize a credit memo with specific invoices applied in SuiteScript, you can use the

record.transform

method to transform an invoice to a customer payment. This is similar to the 'Accept Payment' button in the UI. Here is a simplified example:

javascript
var invoiceId = '123'; // replace with your invoice internal id
var invoiceRecord = record.load({
    type: record.Type.INVOICE,
    id: invoiceId
});

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

// Loop through the apply sublist and select the records to apply the payment to
for (var i = 0; i < customerPaymentRecord.getLineCount({sublistId: 'apply'}); i++) {
    customerPaymentRecord.selectLine({sublistId: 'apply', line: i});
    customerPaymentRecord.setCurrentSublistValue({sublistId: 'apply', fieldId: 'apply', value: true});
    customerPaymentRecord.commitLine({sublistId: 'apply'});
}

var customerPaymentId = customerPaymentRecord.save();

This script loads an invoice record, transforms it into a customer payment record, and then loops through the 'apply' sublist to select the invoices to apply the payment to. Finally, it saves the customer payment record. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
