Hi Experts,

Is there anyway to have a system where there is no work schedule defined at any level of hierarchy. I understand that if there's no work schedule defined at any upper levels of the hierarchy like Assignment, job etc, then the Enterprise level work schedule will be considered for Absence duration calculation. But what happens if there is no work schedule defined at Enterprise level as well?

Thanks in advance!
