Why would certain field changes not show in the System Notes area?

AI generated answer (using internal Slack threads):

****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ****** Certain field changes may not show up in the System Notes area due to several reasons: 1. Only changes are logged: If a field is set to the same value it already had, it will not register a new system notes entry. System Notes only logs changes, not the setting of the same value. 2. Not all fields are captured: Some native fields and custom fields may not show changes in the System Notes. For example, changes to the 'Ship Complete' checkbox on a Sales Order may not be logged. This could be because the field does not have a financial impact, which is a criterion for logging in System Notes according to the NetSuite Help Center. 3. Changes to list values are not logged: If you have a custom field on a record that sources from a list of values, and you edit the value in the list itself, this change wouldn't appear in the system notes of the record. This is because you're not technically changing the referenced Internal ID of the list value, so NetSuite doesn't count that as a change to display in System Notes. Please note that these are general observations and may not apply to all scenarios. It's always a good idea to test and verify in your specific NetSuite environment.
