Using Human Tasks from BPM using barcode creator for jvm control to generate, create code 3 of 9 image in jvm applications. 2 of 5 Industrial In BPM Studio, a Human T jar Code 3/9 ask is added to a business process by dragging and dropping the Interactive Task activity from the component palette onto the process flow. The Participant is set automatically to the role associated with the swim lane into which the Interactive Task is dropped. There are five different Interactive Task activities in the palette that set different Participant patterns for common assignment and routing patterns and a sixth Interactive Task used for complex patterns.

A Human Task has three parts to it: Interactive Task activity Task definition The task form for the browser user interface. In the Interactive Task properties, the process variables are mapped to and from the task payload to specify the data provided to and received from the human participants. In addition to the participant, the task definition includes the data payload associated with the task, notifications, routing, and other properties. The task definition is stored outside of the business process in a separate task file and is reusable by other processes.

In addition to triggering and waiting for the task completion, the process may choose to receive finer grained events during task execution and react to them.. [ 372 ]. 15 . Every Human Task has to Code 39 Extended for Java be bound to a task definition. You can either browse for existing task definitions or create one on the fly. Multiple Interactive Tasks can share the same Human Task definition.

The user interface is an ADF form which binds the task payload to the form data controls. The form can be generated automatically, which is especially helpful during development and testing. Later, for production, the form is usually customized for the purposes of the business process.

. Human Task participant patterns The following are the se swing barcode 3 of 9 t of selected Human Task patterns provided by Oracle BPM Studio. These are based on the Interactive Task BPMN construct and makes it easy for the designer to use the different participant patterns. These are shortcuts for the designer.

Any of these could be defined manually by setting the correct property values during task creation. Initiate Task (User Initiate Task) when this type of task appears in a swim lane, the users who have that swim lane role see a link in Workspace to initiate the process. User Task (Single Approver) this is a simple pattern where the participant is defined by the swim lane.

This is the default pattern. Management Task (Sequential Management Chain) this pattern is a set of users defined by a specified number of levels of management. Voting Task (Parallel Voting Group) with a voting pattern, the users receive the task at the same time and the process waits until the specified number of tasks are completed.

FYI Task (FYI pattern) with this pattern, the process does not wait for task completion but continues on ahead. Complex Task (for combination patterns) here is where the designer can specify pattern combinations; for example, Management Chain and FYI might be used to inform but not wait for one user but the process does wait for the managers to complete the task..

A Human Task Participant List specifies who gets the task assignment. Except for the Complex Task, for all of these patterns, the participant is defined by the swim lane role. For the Complex Task, specify the Participant List using combinations of participant patterns and users or groups specified by value or expression.

. [ 373 ]. Using Human Task Patterns and Other Concepts Human Task completion outcome When a user completes a Human Task in the browser worklist application, the Human Task has a result value called Outcome. The user selects the desired outcome to complete the task. The outcome determines what happens next in the process.

The designer uses the outcome for conditional branching. There are predefined outcomes as well as custom outcomes. A custom outcome is a string value added during the task definition.

Predefined outcome choices are: YES, NO, OK, APPROVE, ACCEPT, REJECT, and DEFER. A custom outcome might be: Submit or Continue. The semantics of the different outcomes are up to the process designer.

A conditional branch can be based on the value of the outcome but where that branch goes and what happens next is part of the process design..
