A Task defines a set of actions that are automatically executed by the system.
Each Task is made up of a number of Task Steps which carry out the individual actions required by the Task.
A task called 'EmailOnAssignment' carries out 2 steps:
1. Send an email to reviewers
2. Send a chase email to reviewers 2 days later.
Execute Task 24 hours before the Submission Deadline.
Execute Task when a submitter completes a submission.
Completing Submission 0012 causes a Task to be executed.
The Task has a Task Step that sends the Submission Completed email.
The Task needs to know to run with the Context of Submission 0012 otherwise it will send the email to ALL submitters.
In order to maintain security, the permissions that a Task runs with are strictly controlled. If the Task does not have the correct permissions to run then it will fail. See Task Security.
