If you need to change a group of employees’ day program for a certain day this can be done from Daily Details, using the Alternate Day Program feature. All employees selected must be changing to the same day program.
1) Load a filter of employees who will all be changing to the same day program on the same day(s) and select All employees in list
2) From the Multiple Actions menu select Day Programs.

3) Select the day program to apply and the date(s) to apply for. If alternate day programs have already been applied and you would like to clear them, tick Reset back to default day program to revert employees back to the day program their assigned shift pattern places them on.
4) Click Apply.
A bulk recalculation for the employees should be performed after changing day programs.
