Adding a new invoice line in existing invoice is not working - php

Question

I am facing a problem while adding a new invoice line in existing invoice from Mysql database.
I have synced the invoice from quickbook to MySql. Two-way sync is working between quickbook and mysql.
The problem is when I add a new invoicline in qb_invoice_invoicline table, It does not sync with Quickbook. Following error I received in qb_invoice table. qbsql_last_errnum 320 last_error_msg
Object "64-1518123234" specified in the request cannot be found. (here 64-1518123234 is the value in qb_invoice_invoiceline.TxnLineID coulmn).If I leave this field blank then there is a parsing error when syncing.
Following is the code I am using to sync.
<?php
error_reporting(E_ERROR | E_PARSE);
ini_set('display_errors', 1);
require_once dirname(__FILE__) . '/QuickBooks.php';

$companyData = json_decode($companyConfig, true);

To summarize the problem what value should be in (qb_invoice_invoiceline.TxnLineID) column to add a new invoiceline ?

Answer 1

If you are trying to just add a line, set the TxnLineID to -1 for all the new line items.
For example, if your Invoice has line items with IDs A/B/C, and you want to append another line, your mod should be something like:
...
<InvoiceLineMod><TxnLineID>A</TxnLineID><InvoiceLineMod>
<InvoiceLineMod><TxnLineID>B</TxnLineID><InvoiceLineMod>
<InvoiceLineMod><TxnLineID>C</TxnLineID><InvoiceLineMod>
<InvoiceLineMod>
<TxnLineID>-1</TxnLineID>
< ... other required values... >
<InvoiceLineMod>
...
If you wanted to delete line B, just send
<InvoiceLineMod><TxnLineID>A</TxnLineID><InvoiceLineMod>
<InvoiceLineMod><TxnLineID>C</TxnLineID><InvoiceLineMod>
