For example:
I create a Route, then I assign an Operation to that Route. Then under the "Resource Requirement" tab of the Operation Grid, I add a "resource type" and select Machine.
My guess is that, this gives D365 the freedom to choose ANY resource type "machine" to perform said operation.

A) Is that correct?
B) If that is correct, has anyone seen a business case in which this was used?
Thanks for any help!
