HOw do I ass a custmom field to the Invoice and CreditMemo Records

AI generated answer (using internal Slack threads):

To add a custom field to the Invoice and CreditMemo Records in NetSuite, you can follow these steps: 1. Navigate to Customization > Lists, Records, & Fields. 2. Choose the type of record you want to add a field to (Invoice or CreditMemo). 3. Click on 'New Field'. 4. Fill in the details for the new field, such as its ID, label, type, and whether it's mandatory. 5. In the 'Applies To' tab, select the record types that this field should appear on. 6. Save the new field. You can also add a custom field programmatically using SuiteScript. Here's a sample code snippet:

javascript
var field = record.createField({
    id: 'custfield_my_custom_field',
    type: record.Type.TEXT,
    label: 'My Custom Field'
});
field.update({
    selectRecordType: {
        recordType: record.Type.INVOICE,
        isOptional: true
    }
});
field.update({
    selectRecordType: {
        recordType: record.Type.CREDIT_MEMO,
        isOptional: true
    }
});

Remember to replace 'custfield_my_custom_field' with your desired field ID, and 'My Custom Field' with your desired field label. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
