For the scheduling feature to work, specific agents need to be enabled and configured in Pega Platform. For more information, see Configuring Pega Robot Manager.
When no scheduled action is defined, the default behavior of the robot is to run in its current work group. When you create a scheduled action for a robot, its current work group is designated as the base work group. After a scheduled action ends, the robot moves back to its base work group.
To change the base work group of a robot, stop the robot, remove all its scheduled actions, move the robot to the designated work group, and then create a new schedule.
