Questions
1. If I enter 'Non Working Days' values, do I need to change 'When Holiday' in my 'Run Time' entry from 'ignore_holiday' to 'suppress execution'?
Yes, but since "suppress execution" when holidays is default behavior for Scheduler , you will not see the "xml" tag in order configuration.
2. I have not defined any global holidays, but are any pre-defined, and would they cause this order to also be suppressed on those days?
No , Until you do not "explicitly" include Holidays-Calendar in your order/schedule it will not have any effect.
