You have attempted an invalid sublist or line item operation. You are either trying to access a field on a non-existent line or you are trying to add or remove lines from a static sublist error on customer refund

AI generated answer (using internal Slack threads):

The error

SSS_INVALID_SUBLIST_OPERATION

is thrown when you are trying to perform an operation on a sublist or line item that doesn't exist or is not accessible. This can happen in several scenarios: 1. You are trying to access a field on a non-existent line: Make sure the line you are trying to access actually exists. You can use the

getLineCount

method to check the number of lines in the sublist. 2. You are trying to add or remove lines from a static sublist: Static sublists cannot be manipulated in this way. If you need to add or remove lines, you should be working with a dynamic sublist. 3. You are trying to access a sublist that doesn't exist: Make sure the sublistId you are using is correct. The sublistId should match exactly with the sublistId in the record browser. Here is an example of how you can check the number of lines in a sublist before trying to access it:

javascript
var lineCount = record.getLineCount({
    sublistId: 'item'
});

for (var i = 0; i < lineCount; i++) {
    var item = record.getSublistValue({
        sublistId: 'item',
        fieldId: 'item',
        line: i
    });
    // Perform operations on item
}

In the first thread, it seems like you are trying to commit a line on the 'item' sublist without making any changes. Make sure you are making some changes before committing the line. In the second thread, you are trying to remove line items from a sales order. Make sure the line you are trying to remove actually exists. In the third thread, it seems like there is an issue with SuiteTax. It's possible that the error is being caused by a bug in NetSuite or SuiteTax. If the issue persists, you may need to raise a ticket with NetSuite. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
