Difference between GL impact being checked or unchecked on a custom segment

AI generated answer (using internal Slack threads):

The GL Impact checkbox on a custom segment in NetSuite determines whether the segment values will be displayed on the GL Impact page for transactions. If the GL Impact checkbox is checked, the custom segment will have an impact on financial reports. It allows you to create a columnar view of your balance sheet or P&L based on that attribute, similar to how you can for department, class, location, subsidiary, or accounting period. If the GL Impact checkbox is not checked, the custom segment will not have an impact on financial reports. It will be used for categorization purposes only, such as tracking a specific business sector. Once a custom segment is created and used in a transaction, the GL Impact checkbox becomes disabled and cannot be checked. This is to ensure the integrity of the financial reports. If you need a custom field to have a GL impact, you would need to create a custom segment instead of a custom field. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******
