Comfirm date and checkbox on PO Lines

The fields circled below - except for providing the ability to track dates, is there any underlying functionality in terms of driving PO commit date activity, or are they simply fields to store data?

We are looking at addressing our supplier commits in a meaningful way in Epicor, and I want to ensure that we don’t put the cart before the horse - and populate a field incorrectly that can help us.

This screen is taken from which version of Epicor ?
