Updating Item Fulfillment Shipping Label

AI generated answer (using internal Slack threads):

Based on the conversations, it appears that when the Integrated Shipping Label is set to true in an Item Fulfillment, clicking on Print Label will generate a label from the integrated shipping service such as UPS/FedEx, not the default Advanced PDF/HTML Template. The label will be in the format provided by the third-party shipping service. If you want to mass update the status of item fulfillment from 'Packed' to 'Shipped', it is possible to do so through a script if you can make the corresponding UI action through the edit mode of a record. As for attaching a shipping label to the item fulfillment record not using the default carriers, it seems you might want to use the 'Printing Shipping Labels' feature in NetSuite. This might entail creating a new preferred Shipping Label transaction form and a related shipping label template. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
