unable to use "Need Date" and "Need Delta"

When purchasing, we’d like to use the “Need Date” and “Need Delta” so as to perform supplier on-time reports…how do we access these fields as they do not seem capable of being populated/modified/updated …

Good Afternoon,

Let me look into this and see if there is anything that can be done to provide a supplier on-time report that you’re looking for. I’ll get back to you with an update as soon as I can.

Thanks,
