why do i get the error "this record does not exist" when trying to save an invoice that is created via the make copy action?

AI generated answer (using internal Slack threads):

The error "this record does not exist" when trying to save an invoice that is created via the "make copy" action can occur due to several reasons. One of the reasons could be that the original record from which the copy is being made has some hidden fields or values that are not visible on the form but are still being copied over. This can cause conflicts or inconsistencies when trying to save the new record, leading to the error. Another reason could be related to the state of the original record. If the original record is applied to another transaction (like an invoice), and you're trying to unapply it during the copy process, it can lead to issues. This is because the record.copy function in NetSuite tends to copy more than just the visible fields and values. It also copies the state of the record, including its applied status. If you then try to unapply it in the new record, it can cause conflicts because the original applied status was also copied over. A potential solution to this issue is to create a new record instead of copying the existing one. This way, you can ensure that only the necessary fields and values are included in the new record, and you can control the applied status as needed. Another solution could be to use a workflow that is triggered on the copy event to clear all the custom fields or any other fields that might be causing the issue.
