Why do long text fields and rich text fields not show a detailed system information when changes are made?

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. ****** Long text fields, rich text fields, and text area fields in NetSuite do not show detailed system information when changes are made due to their inherent design. These fields are designed to hold large amounts of text data, and as such, the system notes new value for these fields is of the free form text field type, which truncates at a string length of 300. This means that any changes beyond the first 300 characters will not be logged in the system notes. This design decision by NetSuite is likely due to performance considerations, as logging every single change in these large text fields could potentially slow down the system. Therefore, if you need to track exact changes in these fields, you would need to come up with a custom solution. One suggested workaround is to use a text area field instead, but this may not be suitable for all use cases.
