TOP_LEVEL_PARENT

The variable is updated or created at the top-level workflow variable scope, allowing a child anywhere in the workflow hierarchy to make a variable available to any other child in the workflow hierarchy, regardless of which level in the workflow the task instances are running.

GLOBAL

A global variable will be updated and or created. Allows for variables to be shared across independent workflows.
