Each workflow step is created in the Process Designer. The step specifies what needs to be accomplished and included in order for the business process to continue.
A workflow step has:
Participants who are individually assigned to complete part of the workflow.
Workflow groups to which work is assigned when it is to be completed by the first available worker in that group.
Responses that can be used to direct routing.
Attachments that provide participants with information they need to complete work.
Data fields, which can be Boolean, Float, Integer, String, or Time. Whether the suit fits is a Boolean field, which means it can be either True or False.
Types of steps
General step: General steps represent an activity that will be processed by a participant or sent to a work queue for processing by participants.
System step: System steps represent built-in functions that will be performed by the system software. The built-in system functions perform logic-control and other functionality in the workflow, such as setting time limits for specific activities in the workflow.
Submap step: Submap steps represent calls to another workflow map.
Component step: Through the Component Integrator, the component step automatically performs actions on the Content Engine, or through custom code, can perform a variety of requests through 3rd party applications.
