Worked example

A complete screen definition for a fictional "SAP system restart" start dialog, showing sections, a table, several field types, validation, and input binding. This screen would typically be the second screen in the dialog, receiving inputs from the first.

Inputs this screen expects

Using {{name}} bindings creates these input parameters, wired in the workflow editor to outputs of an earlier screen or script step:

Input	Type	Example value	Used for
systemName	text	"PRD"	Interpolated into the section title
isProduction	boolean	true	Shows/hides the approval section
defaultJobs	integer	4	Default for the parallel jobs field

What the user sees

• Restart options for PRD: the title interpolates {{systemName}}. The user picks an SAP system, a restart mode (pre-selected to Soft restart), a parallel-jobs count defaulting to 4 (from {{defaultJobs}}), a notification toggle showing "Send notification / Restart silently", and an optional start time that cannot be in the past.
• Production approval: only appears because isProduction resolved to true. The change ticket must match CHG-###### (the help text explains the format, as required whenever regex is set); the approver password is masked and stored encrypted.
• Pre-restart checks: an optional table pre-filled with two rows; the user can edit, add, or remove rows, each with a text column and a boolean column.

What the workflow receives

Each field ID becomes an output parameter; the table produces a single output named after its ID:

Output	Variable type	Example value
target-system	SAP system	the selected system's ID
restart-mode	String	soft
parallel-jobs	Integer	4
notify-users	Boolean	true
start-at	String (date-time)	2026-07-04T22:00
change-ticket	String	CHG-004711
approver-password	Password (encrypted)
pre-checks	String (table rows)	the entered rows

If isProduction had been false, the approval section would not be shown, its required fields would not be enforced, and change-ticket / approver-password would simply be absent from the outputs (they define no default values).
