The fallback rules are designed to work with the three variables, which by default are:
Key Activity: Absence request period.
Key Date: Absence start date.
Period of availability for the primary authoriser: Default = two days before.
By default, the system checks the primary authoriser’s availability based on the absence start date, not the date the request is submitted.
A common misconception is that the authoriser’s availability is evaluated at the point of submission. In reality, a fallback authoriser is only triggered if the primary authoriser is unavailable at least two days before the absence begins.
If an existing request needs to be sent to a different employee, you can manually reassign it in the workflow log.
