Action Requests
In most instances, a batch process runs with minimal human interaction.
Occasionally, people need to make decisions about a process while it runs. To
accomplish this task, OSx uses action requests that enable an operator to
interact with a process.
Action requests are system components that help control a process. With
action requests, the operator can actively and effectively interact with a
batch process from a central location.
During batch processing, action requests provide the following interactions:
They inform the operator about the status of the process.
•
They allow the operator to stop the process and perform quality checks,
•
product analysis, and other hands-on tasks.
•
They prompt the operator for specific responses and
acknowledgements.
