update an external ID without doing a csv

However, please note that it's not possible to blank out an external ID once it's set. Your only option is to set it to a random value. Here's a general idea of how you can do it: 1. Load the record using

record.load

method. 2. Set the new value for the external ID using

record.setValue

. 3. Save the record using

record.save

. Here's a sample code snippet:

javascript
var record = require('N/record');

var myRecord = record.load({
    type: record.Type.CUSTOMER, 
    id: 'internalId'
});

myRecord.setValue({
    fieldId: 'externalid',
    value: 'newExternalId'
});

myRecord.save();

Please replace

'internalId'

and

'newExternalId'

with your actual internal ID and new external ID respectively. Remember, this is just a basic example. Depending on your specific use case, you might need to add error handling, logging, or other functionality.
