Flows for APEX Concepts and Features

Concepts and Features Guide

This section covers some of the key the concepts and features of Flows for APEX.

Topics

Key Concepts

• About Subflows - how we track where we are in the process…
• Logging Philosophy and Lifecycle - explains how Flows for APEX balances run-time visibility, archiving, and purging.
• Transaction Model - describes how Flows for APEX implements transactional control of workflow execution
• Model Versioning - process definitions are versioned, allowing processes to evolve while process instances continue running.

Process Variables, Task Parameters, and Variable Expressions

• Process Variables - explains the process variable system

• Task Parameters - explains task-level inputs and outputs, and how they differ from process variables.

• Input Parameter Layout Guide - quick reference for JSON Region layout properties used when rendering task input parameters.

• Variable Expressions - essentially “triggers” that fire before and after each process step.

• Variable Scoping - once your processes become complex, we use scoping to keep different variables with the same name separate.

Message Flow, Process Collaboration, and Inter Process Communication

• Introduction to BPMN Message Flow and Process Collaboration - introduces process collaboration

• Message Flow Concepts How Message Flow works.

• Message Flow - Message Design An example of how to design your message flow messages.

Adhoc Sub Processes for Knowledge Workers and Autonomous Agents

• Adhoc Sub Process Concepts - explains how Adhoc Sub Processes manage currently startable activities, current situation, and completion.
• AI-Driven Adhoc Sub Processes - explains the recommendation, hybrid, and autonomous control modes built on the Adhoc Sub Process base.

BPMN Iterations and Loops

• About Iterations and Loops Introduced multi-instantiated activities and loops. (An Enterprise Edition Feature).

• Iterations and Loop Concepts - explains how BPMN iterations and loops can be used in Flows for APEX

About Time and Timers

• Timestamps and Timezones Today’s business processes typically involve users in multiple timezones. Some guidance…

• About Timers and Scheduling. details the process timer and scheduling system used to implement timers for reminders, delays, and time out periods.
