Alias set of previous performer The server refers to the alias set assigned to the
performer of the previous activity. Use this option, for example, if this activity
needs to be performed by the Manager of the previous activity’s performer. If,
at runtime, the previous performer does not have an associated alias set, the
server will use the alias set belonging to the previous performer’s group. If
the group does not have an alias either, the failed activity task is sent to the
workflow supervisor.
How can I assign an alias to a user?
