What does this mean "Details: Items you have requested in the record have been deleted since you retrieved the form"

AI generated answer (using internal Slack threads):

The error message "Details: Items you have requested in the record have been deleted since you retrieved the form" typically occurs when you are trying to save a record (like a Sales Order, Purchase Order, or Inventory Detail) in NetSuite, and one or more of the items on the record have been deleted in the system after you retrieved the form but before you attempted to save it. This could happen if, for example, you opened a form to create a new Sales Order, and while you were filling out the form, another user deleted one of the items you added to the order. When you then try to save the Sales Order, NetSuite checks the current status of all items on the order and finds that one or more of them no longer exist in the system, hence the error message. To resolve this issue, you would need to refresh the form and ensure that all items you are adding to the record still exist in the system before attempting to save the record again. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
