About subsessions

A
subsession
starts when a subroutine runs and continues until reaching the maximum lifetime specified in the subroutine properties, or until the session terminates. A subsession populates subsession variables that are available for the duration of the subsession. Subsession variables and events that occur during a subsession are logged.
Multiple subsessions can exist at the same time. The maximum number of subsessions allowed varies across platforms. The total number of subsessions is limited by the session limits in APM (128 * max sessions). Creating a subsession does not count against the license limit.
