can you copy previous on an existing sales order line? if not how could you copy previous

AI generated answer (using internal Slack threads):

In NetSuite, there isn't a direct way to copy a previous line on an existing sales order. However, you can achieve this by using SuiteScript. When a user clicks on the 'Copy Previous' button at the line level on a record, the only event that is fired is a fieldChanged on the department field. You can use this event to populate a field value on that line. Here is a sample code snippet that you can use as a reference:

javascript
function fieldChanged(context) {
    if (context.fieldId === 'department') {
        var currentRecord = context.currentRecord;
        var lineCount = currentRecord.getLineCount({sublistId: 'item'});
        for (var i = 0; i < lineCount; i++) {
            var department = currentRecord.getSublistValue({sublistId: 'item', fieldId: 'department', line: i});
            if (department) {
                // Copy the value to your field
                currentRecord.setSublistValue({sublistId: 'item', fieldId: 'your_field', line: i, value: department});
            }
        }
    }
}

Please replace 'your_field' with the actual field ID that you want to populate. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
