Screen flows in offline mode

Screen flows can be used to perform back-to-back assignments when offline.

• Decision shapes with Boolean expressions (no when rule) are supported.
• Screen flows can contain only assignment, decision, or simple questions shapes. If the flow contains any other type of shape, offline users cannot continue past the assignment that precedes the unsupported shape. In addition:
  • The only exception is a decision shape based on a simple expression that can be run on the client. This shape will work in offline mode.
  • Utility shapes can be at the end of the screen flow. The utility does not run when offline, but becomes available online when the completed assignments are synced to the server.
  • Only assignment shapes can be performed while offline. If any other shape is reached, the flow processing stops when offline.
• You can include custom JavaScript code to execute some basic business logic before and after a flow action is rendered in offline. This is accomplished by adding your own JavaScript code into a custom user scripts bundle. Its functions must be called within a try/catch clause. The JavaScript code to be executed before a flow action is rendered is always called after ClientCache and before the DisplayHarness is called. Pre-activities and post-activities can also run when the flow is syncing to the server.
• Back-to-back assignments are supported, but you must use the default Back button in the screen flow harness. The Back button returns you to the previous assignment as defined in your screen flow.
• You set a flow result using the JavaScript pega.process.flow.setFlowEndStatus() method. This method is used to override the status set using a property in the subflow's end shape. The offline process engine takes into account the likelihood setting if the flow result is conflicting or is absent, provided it is not in a subflow.
• The completed datetime recorded in the audit trail is the datetime that the assignment completes on the server when the item is synced when back online.
