can not add a new line to a partially fulfilled sales order without getting this error 024013

AI generated answer (using internal Slack threads):

The error 024013 you're encountering when trying to add a new line to a partially fulfilled sales order might be due to the fact that NetSuite does not allow modifications to a sales order that has already been partially fulfilled. This is because the sales order is in a 'pending fulfillment' state. In the context of SuiteScript, when a sales order is partially fulfilled, it is considered as 'locked' and cannot be edited. This includes adding new line items. The system throws an error to prevent any changes that could potentially disrupt the fulfillment process. If you need to add a new line to the sales order, you might need to cancel the existing fulfillment, add the new line, and then re-fulfill the order. However, this could have implications on your inventory and accounting, so it's important to consider all aspects before proceeding. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
