C-1112 Many computer input procedures are most effectively handled by presenting a user with a series of simple forms that each require only one or a few questions to be answered. After submitting a form, a user receives with another simple form (with more questions) that may depend on previous answers. At any point, users can backtrack to review, or change, previous answers.
Process Commander can support such interactions with screen flows, a flow rule with specific settings.
Three runtime presentations are available to allow users to navigate within a screen flow execution at runtime:
To see and interact with an example flow that uses the breadcrumbs control, select> Integration > Import > Rule from File. byrnb 2/25/10
To see and interact with the tabbed presentation, select> Process and Rules > Find Rules > Find by a Custom Field. byrnb 2/25/10
The standard flow rule PegaSample-CustomerRequest.CustomerFeedback provides another screen flow example. For example, these flow actions appear in one sequence of use of this rule:

To make a screen flow, create a new flow rule and
select ScreenFlow
in the Template
field.
A screen flow rule cannot be a starter flow rule. Use a regular flow to create the work object. Then call the screen flow as a subflow.
The standard harness rule Work-.PerformScreenFlow is by default used to present the assignments in a screen flow rule. You can override this rule; the standard harness rules Work-.TabbedScreenFlow and Work-.TreeNavigation provide alternative presentations.
A screen flow rule must have at least one task marked as entry point. Typically, screen flow rules have multiple tasks marked as entry points; these are places in the flow that a user can return to using the Back button.
A screen flow can operate on a temporary work object, one that is never saved to the database. C-1884/KHATV clinic/03/01/05
