Netsuite Beforesubmit/Aftersubmit script not saving - netsuite

Question

I am New to Netsuite.
I am trying to archive the following functionality,
I created a code that will create an Invoice through API - (Completed & worked).
I want to change the Tax values to zoho for the Invoice that is created through the above.(ISSUE)
Here is my following code:
define(['N/log'], function (log) {
/**
* User Event 2.0 example showing usage of the Submit events
*
* #NApiVersion 2.x
* #NModuleScope SameAccount
* #NScriptType UserEventScript
* #appliedtorecord customer
*/
var exports = {};
function beforeSubmit(context) {
try
{
var currentRecord = context.newRecord;
log.debug({
title: 'currentRecord',
details: currentRecord
});
var sublistName = "item";
var sublistFieldName = "taxcode";
var line = context.line;
var subsidiary_id = currentRecord.getValue({fieldId:'subsidiary'});
var inv_type = currentRecord.getText({
fieldId: 'custbody3'
});
log.debug({
title: 'inv_type',
details: inv_type
});
log.debug({
title: 'subsidiary_id',
details: subsidiary_id
});
if (subsidiary_id == 6)
{
if (inv_type == "Services") {
if (sublistName === 'item') {
var lines = currentRecord.getLineCount({sublistId: 'item'});
log.debug({title:'lines',details:lines});
for (var i = 0; i < lines; i++) {
var descriptionValue = currentRecord.getSublistValue({
sublistId: sublistName,
fieldId: "description",
line: i
})
log.debug({
title: 'descriptionValue',
details: descriptionValue
});
log.debug({title: 'sets',details: /NON-JP/ig.test(currentRecord.getSublistValue({
sublistId: sublistName,
fieldId: "description",
line: i
}))});
if (/JP/ig.test(currentRecord.getSublistValue({
sublistId: sublistName,
fieldId: "description",
line: i
})))
{
currentRecord.setSublistValue({
sublistId: 'item',
fieldId: 'taxcode',
value: 6880,
ignoreFieldChange: true,
enableSourcing: true,
line: i
});
currentRecord.setSublistValue({
sublistId: 'item',
fieldId: 'taxrate1',
value: "10.0",
ignoreFieldChange: true,
enableSourcing: true,
line: i
});
}
currentRecord.setSublistValue('item', 'taxrate1', i, 10.0);
}
}
}
}
} catch (e) {
log.error('Error in validateLine', e);
}
}
return {
beforeSubmit: beforeSubmit
};
});
The Code logic and getValue method and other functionalities are working perfectly Except for submit
I tried to submit the newlyu updated line value in netsuite but the record is not getting submitted.
Can you help me to identify the issue I am doing.
Thanks in advance

Answer 1

Remove the ignoreFieldChange and enableSourcing parameters from your setSublistValue calls. I am not sure if your logging statements will work -- we typically always convert the details field to a string before logging, by using something like JSON.stringify.
You'll also want to check the script deployment for the logging there to make sure there aren't any syntax errors or other exceptions being thrown.

Answer 2

You're setting the variable line at the beginning to context.line but the current context is beforeSubmit, therefore, it will be undefined. I can see that you're not using this variable anywhere but it is worth noting that. line is only available in Client contexts such as fieldChange, validateField, and such...
Also, in the last setSublistValue you're providing several parameters when the Record.setSublistValue method receives an object, just like you did on the previous setSublistValue calls.
