Substitution is a feature of the UWL that allows you to take over items from other users (on a due-course basis as well as in case of an emergency) and to assign items to other users (that is, to give other users permissions to take over items). These cases are defined by certain substitution rules, which can be managed through the Substitution screens.
For more information, see Substitution.
From the details area, you can follow-up on a task. From the follow-up UI, you can enter a date manually or choose date to assign for follow-up on the task.
