Hello.
In this case, the employee works alternating morning and evening shifts, so first week morning and second week evening ect. The employee's schedule is defined in the "Employee Schedule and Rules" section, which specifies which shift the schedule starts from.
For this employee, it is specified that the schedule starts from the morning week shift. When I try to create Substitute Schedule for him where a holiday sets on an evening week shift, the system sets a morning shift for the holiday, because it selects the shift from the "Employee Schedules and Rules" page at the Shift section, even though I defined in the substitute schedule that it should be an evening shift.
Basically, it doesn't matter what is defined in the substitute schedule's Shift section, because the system determines the shift for the day based on the Shift section in the Employee Schedules and Rules.
I hope I was able to explain the problem clearly, and that someone might be able to help with this issue.
