We recently started working with Projects in NetSuite. Are there no System Notes for Projects? I can’t see where to turn those on in the custom form for a Project.

Do you have the "new UI" enabled in general preferences?

I just tried this but it still doesn’t seem to enable System Notes.

Is the system information tab hidden on the form?

Yes, it’s there, showing the Active Workflows and Workflow History, but no System Notes subtab and in the form customisation I don’t see a place to enable the System Notes like I do on forms for other record types.
