how to change the item fulfillment item

AI generated answer (using internal Slack threads):

To change the item in an item fulfillment, you would typically need to delete the existing item fulfillment, make the necessary changes to the sales order, and then create a new item fulfillment. This is because once an item fulfillment is created, certain fields become locked and cannot be edited directly. However, if you're looking to change the status of an item fulfillment (for example, from 'Packed' to 'Shipped'), this can be done through scripting if you can perform the corresponding UI action in edit mode of a record. Please note that an item fulfillment is a posting transaction and will reduce the quantity on the committed items for that specific transaction unless you re-allocate. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
