6.1 - eScheduling

Can anyone explain how eScheduling treats Additional and Auxiliary
Reources under the Advanced button on BOM's and Jobs? The "Help" says
that they are used by eScheduling, but it doesn't explain how. I've
asked Vantage Support, but they are having to research (???) this
function. Any info from the collective will be most appreciated.
