Why are the Tax Rate and Options sublist fields disabled and unable to change their Show/Hide checkbox when configuring custom transaction forms? How can I show/hide these sublist fields on the Items sublist?

AI generated answer (using internal Slack threads):

The Tax Rate and Options sublist fields are system fields and are disabled by default in NetSuite. This is because these fields are tied to the system's tax calculation functionality and are not meant to be manually adjusted on a transaction level. However, if you want to show or hide these sublist fields on the Items sublist, you can do so by customizing the form. Here are the steps: 1. Navigate to the transaction form you want to customize. 2. Click on Customize > Customize Form. 3. In the Screen Fields subtab, navigate to the Sublists subtab. 4. Here, you can check or uncheck the Show checkbox for the fields you want to show or hide. Please note that this will only affect the visibility of the fields on the form. It will not enable you to edit the Tax Rate and Options sublist fields as they are system fields. If the fields are not available in the Screen Fields subtab, it might be due to a script or workflow that is controlling the visibility of these fields. In this case, you would need to modify the script or workflow to change the visibility of the fields. ****** Disclaimer: This response was generated by an artificial intelligence assistant based on previous conversations from multiple Slack channels, and may contain inaccuracies or mistakes. ******

I just told you I can't click the checkbox on the form customization page.
