add a new item to subscription how go generate invoice for new item

AI generated answer (using internal Slack threads):

To add a new item to a subscription and generate an invoice for it, you would need to follow these steps: 1. Add the new item to the subscription. This can be done through the NetSuite GUI by using an Add-on catalog type. The item will not be added to the subscription plan or price book. 2. Once the item is added to the subscription, you would need to create a price plan for the new item. This can be done through scripting. 3. After creating the price plan, you can add the item to the subscription via a subscription line and/or price interval. This can also be done through scripting. 4. Once the item is added to the subscription and the price plan is set, you can generate an invoice for the new item. This can be done using a SOAP request in .Net. You would need to call Initialize with the Sales Order ID as the initRef and the initType as Invoice. Please note that this process may require advanced knowledge of scripting and SOAP requests.
