Hi! I want to create a script that updates line number in a custom field on sales orders. I tried myself and then with chatgpt but I get the same error all the time. It works after I re-edit and save the order, but not on the first save. I have tried the same approach but with afterSubmit and that doesn’t give me anything at all. /** ◦ @NApiVersion 2.1 ◦ @NScriptType UserEventScript ◦ @NModuleScope SameAccount */ define(["N/record"], function (record) { function beforeSubmit(context) { if (context.type === context.UserEventType.CREATE || context.type === context.UserEventType.EDIT) { var newRecord = context.newRecord; // Check if the record is a sales order if (newRecord.type === record.Type.SALES_ORDER) { var lineCount = newRecord.getLineCount({ sublistId: "item" }); // Loop through each line in the "item" sublist for (var i = 0; i < lineCount; i++) { var lineNum = newRecord.getSublistValue({ sublistId: "item", fieldId: "line", line: i }); // Set custcol_line_number = line number newRecord.setSublistValue({ sublistId: "item", fieldId: "custcol_line_number", line: i, value: lineNum }); } } } } return { beforeSubmit: beforeSubmit }; }); What am I doing wrong?

Do you know suitescript? I don’t think we should support ChatGPT generated code at all.

Maybe not, however, what is wrong with this code? if you log.debug the value of lineNum in each iteration, what is it on create?

It’s before submit .. you don’t have line number before after record submit As such, you won’t be able to access the line number field in a beforeSubmit script, which is why your code is failing on the first save but works when re-saving the record.
