Key Concepts

The following list contains definitions of key concepts that are essential in understanding the JD Edwards EnterpriseOne Workflow. Before you create a JD Edwards EnterpriseOne Workflow process, you should familiarize yourself with the following concepts:

JD Edwards EnterpriseOne Workflow system

All of the tools that facilitate the design of a JD Edwards EnterpriseOne Workflow process, as well as the JD Edwards EnterpriseOne workflow engine.

JD Edwards EnterpriseOne Workflow engine

All of the JD Edwards EnterpriseOne mechanisms that move a JD Edwards EnterpriseOne workflow process from one task to another.

Process definition

A template or model of a JD Edwards EnterpriseOne workflow process. The process definition contains all the information about the tasks, transitions, and conditions that make up a JD Edwards EnterpriseOne workflow process. That is, the process definition defines each component of the process and defines each path that the process might follow.

Process instance

An active process in the system. When an event rule activates a JD Edwards EnterpriseOne workflow process, the system creates a process instance. The process instance follows a path that is defined in the process definition. You can have several concurrent process instances of the same process in the system.

Note: If you are familiar with object-oriented programming, a process definition is comparable to a class and the process instance is comparable to an object.
Process version

A specific JD Edwards EnterpriseOne Workflow process definition. The system uses process versions to enable modification of processes without disrupting currently running process instances. Before you modify a process, you should copy the JD Edwards EnterpriseOne workflow process version to a new version number, edit the new version, and then make the new version active. Use this versioning mechanism during JD Edwards EnterpriseOne workflow development to enable process instances that started using the old version to finish using that same version.
