on a custom record, I need a field that will calculate the difference of two other fields on the same custom record when another field is updated

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** To calculate the difference between two fields on a custom record when another field is updated, you can use a combination of SuiteScript and workflows in NetSuite. Here's a general approach: 1. Create a custom field on your record to store the calculated value. This field can be of type integer or decimal, depending on your needs. 2. Create a User Event Script or Client Script that calculates the difference between the two fields and sets the value of the custom field you created in step 1. This script should be triggered when the field you want to monitor is updated. Here's a simplified example of what the SuiteScript might look like:

javascript
function fieldChanged(context) {
    if (context.fieldId === 'field_to_monitor') {
        var record = context.currentRecord;
        var field1 = record.getValue('field1');
        var field2 = record.getValue('field2');
        var difference = field1 - field2;
        record.setValue('custom_field', difference);
    }
}

3. Deploy the script to the appropriate record type. 4. If you need the calculation to occur before the record is loaded, you may need to use a workflow with an 'After Record Submit' trigger. Please note that this is a simplified example and you may need to adjust it to fit your specific needs. Also, remember to thoroughly test any changes in a sandbox environment before deploying to production.
