when pressing Receive button in Purchase order, in what mode is the item receipt (create, copy or edit)

AI generated answer (using internal Slack threads):

When you press the "Receive" button in a Purchase Order, the mode of the Item Receipt is "Create". This is because you are creating a new Item Receipt record based on the items received from the Purchase Order. In NetSuite, the Item Receipt is a transaction that allows you to keep track of the physical incoming delivery or receipt of goods and even services. It is used to record the receipt of items from a Purchase Order. If you need to disable line fields based on a field of the user record when the "Receive" button is clicked, you should use a before load user event script deployed on the item receipt. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
