In order to correctly and completely transfer tasks from one user to another, several steps must be followed.
A user must create his/her absence correctly in his/her user profile. See Absence.
An absence rule must be created for the processes for which the tasks are to be completed by another user.
The timer in the Admin Client HandleActualAbsence must be created in order to pass the tasks. See Create timer. It ensures that all tasks will be passed according to the previously established rules.
