The chronological execution of a workflow can be monitored with time checkpoints. You can only use this type of runtime monitoring in workflows.
Specify the time checkpoint by indicating
An object that is defined in the Checkpoint tab (such as a notification) starts if a workflow task has not started until the specified point in time.
If time checkpoints are assigned to a workflow, they become active when the workflow is activated. This is especially important if you use the generate at runtime option.
